Review: LEGO 31120 Medieval Castle

LEGO have been absolutely slaying the game when it comes to large, ambitious 18+/Creator Expert sets, and doubling down on nostalgia in 2021.

Following the very positively received launch of the Medieval Blacksmith early this year which brought back the Black Falcons faction, and the resurgence of Vintage Castle thanks to its strong showing in the 90th Anniversary Fan Vote, it’s been quite a renaissance year for Castle.

Bonus reading: check out my interview with Medieval Castle designers Wes Talbott and Austin Carlson to geek out on all things vintage and Castle.

The rumour mill went into overdrive when LEGO teased a mini-Castle in the designer interview, and fans were expecting LEGO to give a classic LEGO Castle the full 18+/Creator Expert treatment, but turns out, LEGO had other plans, and here we have this year’s 31120 Medieval Castle, which sits within the Creator 3-in-1 theme.

The reveal post was one of the most popular and talked about posts on the blog this year, and it seemed that fans were split and unsure about the Medieval Castle being a basic Creator 3-in-1 set, and I had similar fears too, but after building the set, I can confidently say that this is a standout set this year.

Read on to check out LEGO 31120 Medieval Castle in more detail!

The new LEGO Creator Medieval Castle will be released in Europe and Asia Pacific from 1 June 2021, 1 August 2021 in the US and will retail for US$99.99 / AU$159.99 / £89.99 from, LEGO Brand Retail Stores, and most toy stores.

It’s been a while since I’ve built a Creator 3-in-1 set, and after a whole slew of detailed, complex 18+ sets like R2-D2, this was a refreshingly chill build – no complicated Technic machinations, or high-level building techniques – just straight forward simple LEGO building.

That’s not to say that the build was boring, but this is obviously aimed at younger kids aged 9+, so it has to remain quite accessible, while at the same time leveraging modern building techniques.

It’s great fun that will last you a couple of hours (on the main Castle build) at a really affordable pricepoint.

Why waste the awesome new Black Falcons torsos and legs introduced in the Medieval Blacksmith? You get 2 Black Falcon knights in the set – a male and female knight (yay gender balance) who are each armed with a spear and shield, and a longbow.

Also included is a random minifigure, who looks like a bum, or peasant but is actually the Castle blacksmith. Or he could be the king, and just enjoys dressing up like a bum to not draw attention.

Here are the back prints on the minifigures, but they don’t have dual-sided heads.

Unfortunately, the Black Falcon knights don’t come with the cool shoulder pauldrons like the ones in the Medieval Blacksmith set.

For a set this size, which will likely remain in Castle form, I feel that only 3 minifigures feels a little lacking, and when displayed, it could really benefit from another 2 minifigs at least – maybe some peasants, or younger children running about the Castle.

Here’s the completed Medieval Castle, and I was wowed when it was finished.

It’s a substantially large set thanks to its height, but also has a fairly compact footprint, which means that if you’re low on display space, it shouldn’t be too hard to fit it in.

The set measures over 10.5 in. (26 cm) high, 12 in. (31 cm) wide and 11 in. (28 cm) deep – the height and “volume” of the Castle is really impressive, and it makes great use of larger-elements and bricks to give it its heft, instead of relying on tons of smaller pieces to pad up the piece count.

What immediately strikes you is just how vibrant and colourful the exterior is – with the use of constrasting brown and yellow walls, red and white banners which give the grey walls some personality and character.

The Creator Castle checks all the right boxes and has all that a good LEGO castle needs – a moat, functional drawbridge, a dragon, and looming parapets and towers on each side of the keep.

There are also some considered features that break up the monotony of the drab walls such as this tree to the side with pink blossoms and small mushrooms growing at the foot, and also mossy cliffs with brown roots emerging out of them on the corners.

The Castle folds together into a compact square, and here’s a look at the left side, which has a stream, and a water wheel which powers the blacksmith.

It looks great, and I especially like the use of transparent cheese slopes to create the effect of rushing water.

Here’s a look at the little cottage/building that awkwardly sits just a little offset from the walls. I kinda like it – it’s not ugly, but looks quite natural and organic, like a building that was built on top of the Castle walls in an unplanned manner.

There’s also a neat weather vane on the Blacksmith’s roof.

Here’s a look at the back of the castle.

There’s a bullseye for archery practice at the back – which is also the home to a family of hens and a rooster – I sure hope the Black Falcon archer has good aim!

I also consider this to be a nod towards Forestmen!

And lastly, here’s the right side which boasts some really nice architectural details, especially the pillars and columns. I was not expecting such mature design language in a Creator 3-in-1 set, and I also love how well the watchtower is constructed using SNOT (studs not on top) techniques for that smooth look.

Swinging back to the front, it might be slightly disjointed, but I like how busy it is.

The red and white banners give the Castle a very regal look, and in my mind are a nod to Lion Knights.

Similarly, I think the yellow and brown colour scheme is a reference to Series 20’s Tournament Knight.

It’s really simple, but the sleek roof tiles are quite nice, and provides a nice burst of dark blue that contrasts great against the yellowish brown walls.

One of the neatest play features is the working drawbridge, which you can raise or lower by turning the dial on the side – there’s also a simple “locking” mechanism in the interior of the building to keep it in place.

Very satisfying, and perfect for when Wolfpack starts sieging the Castle.

What’s really neat about the Castle is just how playable it is. It has 2 modes – folded up where the Castle collapses into a tight square footprint, or can be opened up like a dollhouse to open up more play possibilities.

You can open it out to create a formidable “wall” setup like this.

Or fold the walls in slightly to play out scenes on the inside of the keep – which is quite charming, and less intimidating than the stoic outer walls of the castle.

It opens up to reveal the interiors of the Blacksmith’s workshop, battlements (walkways) for Black Falcons to patrol, a small fruit stall and some other fun little hidden features.

To feed the Castle inhabitants, there’s a small unmanned stall here with fruits, and a baguette.

There’s a solitary jail cell with a poor skeleton inside. Guess the Black Falcons are the type of faction to conveniently forget to feed their prisoners.

Having copious amounts of food next to the jail cell is an extra level of pettiness that I didn’t know was possible in a LEGO set.

Here’s a look at the Blacksmith’s Workshop, which has a suit of armour ready to go, as well as a sword that’s being forged.

The water wheel comes in handy here, as you spin it, it operates the blacksmith’s hammer to automate the forging process, which is pretty clever for a guy who looks like his favourite hobby is drinking too much ale on the weekend.

I really enjoyed this simple mouse and cheese scene on the stairs, just outside the Blacksmith’s workshop.

Beneath the stairs is another classic Castle staple – a treasure chest with jewels and bars of gold inside.

The last thing that caught my eye in the main section of the Castle is this privy chamber aka a medieval toilet. It’s fairly unassuming, tucked in a dark corner but the roll of toilet paper gave it away!

Last but not least, the build ends on a fantastical note by assembling this fully brick-built dragon. It uses ball joints for posability, but I found it quite fiddly and unbalanced, although I do like design used for its head – especially its angry expression.

Is it better than the classic LEGO dragon? Absolutely not, but it’s a fun exercise to build the dragon out of bricks that younger builders can enjoy.

That said, the dragon does introduce even more playability to a set that has playability and roleplay absolutely bursting from its gills.

Being a Black Falcon castle, I had to obviously call in some reinforcements, as there’s just so much space to go around.

I have to say, the interiors look so much better with more minifigures filling it up.

What I liked:

  • An excellent collision of old and new LEGO
  • So much value packed into a really affordable set
  • Black Falcons!
  • Looks terrific on display
  • Great working play features
  • You may be tempted to purchase 3 copies

What I didn’t like: 

  • Only 3 minfigures isn’t quite enough
  • Castle wall locking mechanism is a little fiddly, and isn’t the smoothest
  • Not a major complaint, but I would’ve liked more references to Classic Castle themes

As a massive fan of all things Vintage LEGO, and Classic Castle, I had my apprehensions when I heard that LEGO was going to take on a Castle as part of its Creator 3-in-1 theme, but all fears disappeared as soon as I started the build.

The most pleasant surprise was just how familiar building the castle felt like – from the folding mechanism which was commonly employed in vintage LEGO Castle, to the layout and selection of colours, the designers did a terrific job adapting norms and tropes from classic Castle, yet were able to make it also feel like a contemporary LEGO set.

The bright vibrant colours might be a sticking point for some, but I like the different colours as it gives the Medieval Castle a pop of personality, and makes for a really eye-catching display piece, rather than a monolith of grey.

The fact that this is a Creator 3-in-1 set, and that there are 2 alternate builds (a Tower + Trebuchet combo and Windmill) ensures that there’s plenty of replayability here, which is ideal for people that don’t have a massive LEGO budget and want to get the most out of their purchases – which is where Creator 3-in-1 shines.

The Black Falcons connection is nice, however one of the glaring weaknesses is the lack of minifigures. Only 3 minifigures to populate what is essentially a large minifig-scale set feels like a mistake here, and the model would have benefited tremendously from some peasants, someone to man the stalls, or even some children running about.

It truly feels stark and empty when you realise you have all this free space, so my advice would be to gather all your old Castle minifigures to populate the Medieval Castle.

Do I want a proper 18+ Castle with a ridiculous piece count and crazy build techniques? Absolutely, but this is a nice stepping stone, and hopefully if this sells really, really well will signal to LEGO that Classic Castle fans are still hungry for more.

This is one of those special LEGO sets that has accessibility as its trump card. It’s perfect for families and young kids, but will also appeal to those wanting to indulge in some Castle nostalgia.

I’m really impressed by the design team’s ability to seamlessly blend the old with the new in such an accessible format. With it being a Creator 3-in-1 set, it will hopefully go on discount regularly which makes it an even more compelling purchase.

This is a strong 4 out of 5 from me, and one of the non-18+ highlights of 2021, and cannot recommend this enough.

To check out the alternate builds, read Brickset’s review which showcases the other 2 alternate builds as well.

Rating and score: 4/5 ★★★★✰

Build [5] – The build blended classic Castle architecture with modern techniques without it being overwhelming or tedious. Plus, you can build 3 variants!
Real Value [5] – Being a Creator 3-in-1, it’s great value – affordable, and you get so much out of it
Innovation [4] – It’s remarkable how much can be achieved with a simple selection of non-specialised elements
Coolness [4] – It looks great on display, and it feels extra cool as it’s been so long since the last LEGO castle.
Keepability [3] – This has the potential to be a great keeper, and is an all-around great set – unless of course LEGO goes full 18+ on a Castle set.

Thanks so much for reading! I hope you enjoyed my review of the Creator 3-in-1 Medieval Castle!

  1. Collin Hartl says:

    I really like the new take on the medical castle kit as it is modern yet vintage at same time and having new figures that are old figures – will help make it easy to add to collections and expand builds whom want to make their own custom castle blend with new and old pieces.

  2. Paul Castle says:

    I think that I shall be ordering three copies of this to build a the massive linked version at some point between now and Christmas, next time a nice GWP or double-points offer is unveiled. I shall also be digging out the old 80s sets to rebuild at some point too, as this was a major favourite when I was 8 years old.

  3. Shelise says:

    Hello! I’m a Mom to a huge Lego fan. His 16th birthday is coming up and he wants this set. I thought it looked a little childish but after reading this review, I guess there is a demand for this type of set. I was hoping to just get on and preorder but that isn’t available. Do you have any insider information on that? Do you know if it will be available for preorder and when? Or do I just have to go on August 1 and get it? Thanks!

  4. Armando says:

    I’m very excited to get this set on August, maybe I’ll get two copies to have the tower with the trebuchet attached to the main build.

    And I’m still hoping LEGO will release one day an “Ancient” or “Classical” theme with sets from ancient Rome, Greece, Persia, Carthage, Egypt, etc; it would be so awesome.

    Great Review by the way!

  5. Lucas says:

    Nice review! Question – I read the height is 26cm. Is this considering also the flags on top of the tower/entry gate? I’m thinking about displaying it in shelf but I just have 25cm available.

    • Jay says:

      Hey Lucas, I double checked and the flag on the tower with blue roof is actually taller! It’s about 27cm tall on that end.

      I think if you’d like to display in a 25cm shelf, you’ll need remove all the flags

  6. Eli says:

    Great review! Excited to get this set to pair with the blacksmith set. Just FYI: the US Lego website says that this comes out on August 1.

  7. Leonie Blake says:

    Still have the original castle we bought for our so wh is now 50 my husband has helped our 3 children build it and also his granddaughter.

    • Paul Castle says:

      I’m 44, so was a little too young to have built the original castle as a child, but a best friend’s older brother had it, and the pieces were handed down big tub of mixed bricks so I remember playing with the figures and building castle walls with the arches. This memory always stayed with me, so when I was 40 I bought the complete set on eBay (although the instructions are just on my computer).

  8. Hans says:

    Based on the 3in1 Pirate ship that often goes on sale for $95 at Kmart, I’ll wait for Kmart to have their sales for this set in the near future 🙂

  9. B.T says:

    Thanks for thre review. Never have any Castle sets so I’ll be picking this up, the question is how many copies should I buy 😀

    • Aldrich Bautista says:

      Depends how big you want to go! I am very tempted to get 3 (at least 2) to build all the alt builds and use the spare parts to add details and make adjustments.

      With three Medieval Castle sets, and the Medieval Blacksmith, a garrison of 10 is doable. (2 + 6 + 2 armored up blacksmiths). The blacksmith from the set would remain.

  10. Gina says:

    I will be getting it, I also hope they do an 18+ version. Love your review, thanks Jay.

  11. Julien says:

    Fantastic review !
    It wll be a must have for me with a small discount and a perfect gift for a little boy.
    I think there are no stickers am i right ?
    Anyway it will be a best seller this year : price, number of parts, 3 builds, colorful, castle theme…and playability !!!
    That’s a rainbow of good points…

    • Jay says:

      Thanks Julien, can confirm – zero stickers! It’ll be perfect for young boys, and the build is relatively easy to follow, so with some assistance (depending on age), it’ll make for a great shared building experience.

  12. James says:

    WOW 🤩! great review Jay! Also I can help but notice that there are ads everywhere and there have never been any ads before. I don’t want to sound like a snobby brat but just letting you know because you said you moved sites just so you didn’t have to deal with ads.

    • Same. They kept popping up and blocking the images, so I just gave up, which is too bad, because Jay always takes good photographs of sets

      • Damien says:

        Yep too many ads

        • Jay says:

          Sorry for the experience! Are you on desktop or mobile? I’ve just started a trial, so any feedback will be valuable.

      • Jay says:

        Hey Terrence, so sorry to hear about your experience. Are you on desktop or mobile? Do let me know so I can know what to feedback and what changes I need to make.

        They technically shouldn’t be blocking or interfering with images, and I’ve also specified that I didn’t want any autoplaying videos ads to keep the reading experience relatively consistent.

        For full transparency, I’m running a trial with advertising to help support the running costs of the site. It’s been a massive year and traffic (and running costs) have ballooned this year.

        I’ve also selected one of the top ad-serving platforms, and have been doing research to ensure that no dodgy ads start flooding the site, and you’ll hopefully only see banners from reputable advertisers.

        Just to put things into perspective, I’ve had about 3-4x the traffic I’ve had this time last year (which was quite high), and I’ve already had to upgrade my hosting bandwidth twice, with another probably coming in the horizon!

        To also prevent any downtime and for proper support, I’ve also started paying for a developer to support on keeping things up and running, and making the site speedy with minimal downtime.

        I do appreciate the feedback, so please keep it coming so I can make tweaks. I’m currently in the pilot phase of setting things up, so any reader feedback is going to be very helpful!

    • Jay says:

      Thanks James! It was a blast to put together, and I’m hoping to do a side by side with another classic Castles soon!

      Thanks for your feedback about the ads – not a snobby brat at all. This is something I’ve been deliberating for quite some time, and I’ve got massive plans/aspirations for this site to scale up my content, which will be quite resource intensive. This is everything from paying contributors/guest writers, to equipment upgrades, and even higher server costs as well.

      Really appreciate any and all input into this. I’ll copy paste what I initially wrote to Terrence below:
