Building castles can be one of the most fun activities to do with LEGO. It lets you create a meaningful structure while at the same time leaving room for creativity and fantasy to happen.

In this post, we have collected the 25 coolest LEGO castle plans. These are plans from both existing sets and MOCS. MOC is an acronym for (My Own Creation), so these are sets that LEGO fans have built themselves and then they are sharing the plans so other people can build them too.

LEGO Original Sets

First, let’s start with the LEGO original sets. From all the castle plans available, we have picked the 16 sets that we thought were the coolest.

71043: Harry Potter Hogwarts Castle

We are starting strong with the Hogwarts Castle. This is, in our opinion, one of the coolest castles available and it will look amazing when finished.

This castle contains 6.020 pieces, so it will be a challenge to build it. When built, the castle measures over 22 inches (58cm) high, 27 inches (69cm) wide, and 16 inches (43cm) deep.

MOC Designs

The next part of the list is about MOC designs. These are designs that are created by LEGO enthusiasts and they are called “My Own Creation (MOC)”.

Sometimes, these sets take as a base a set from LEGO and expand on it. Other times, they are completely new creations. We have found 9 that we really like. But you can always go to Rebrickable to check some by yourself.

MOC – The Modular Knight’s Castle

This castle was built by LEGO enthusiast klockizbroda. It is a simple yet engaging castle with modules that can be easily rearranged in order to create several shapes without having to completely dismount the castle and mount it again.

The castle consists of 6 main modules which, when rearranged, will create the different shapes mentioned above. These are the six modules:

  • Hinged walls: These will help you shape the castle in any manner you want.
  • Tower bases with windows and plenty of room inside.
  • Half battlements for creating short towers.
  • Middle tower segments for creating tall towers.
  • Full battlements for crowning the tall towers.
  • Main gate with a working drawbridge and portcullis.

In addition, you can also build a siege tower with a folding bridge that reaches the top of the walls and can be used to attack the castle. If you want to find the instructions to build this, follow this link and check the “Building Instructions” tab under the explanation of the MOC.

MOC – Löwenstein Castle & Official Expansion

This one is actually a combination of two MOCS in one. The first one is the Löwenstein Castle, a MOC that can be found here and that won a prize and became a manufactured set on its own. The same designer, Raziel_Regulus, has also done an expansion. The combination of both is even better than the first design, so that is why we feature them together.

The expansion finishes off the design and it adds the following spaces:

  • A storage room, next to the kitchen
  • An alcove with a private chapel for the lord’s family
  • A half-timbered house with sleeping quarters for the castle’s common folk
  • A vault with an armory
  • An underground pond, expanding the castle’s secret wine cellar
  • A watchtower
  • Another crenelated wall
  • A small jetty on a pond for fishing
  • Two additional spruces

The instructions for the expansion are actually not free, but you can check it out here to see if you want to purchase them.

MOC – Castle Rebrick

The idea behind this castle was to reuse the sets that the creator had and as a tribute to the LEGO castle sets from the 80s and 90s. The creator, John_Legotti, had around 4000 pieces at his disposal from all his old sets but ended up using only 2986.

Most pieces used are quite common, with the exception of two raised baseplates. If you want more information about this MOC or to know which sets and pieces the creator used, you can check it by following this link.

MOC – The Castle Gray

This MOC castle was done by Bejkrools. This castle features the following main areas:

  • Bascule bridge
  • Hidden cave
  • Water well
  • Smithy
  • Small stable
  • Archery training place
  • Dining room
  • Library room
  • Throne room
  • Two living rooms
  • Armory
  • Dungeon with prison
  • Treasure chamber

The castle has four parts that can be hinged, which means that it is comfortable to access the interior even for adults.

MOC – The orange castle

This MOC castle, designed by gabizon, is one of my favorite MOC castles because of how different it is from the others. The orange roofs give it a fresh look, very different from the typical medieval feeling that this type of construction usually has.

This MOC needs 1007 parts to be built. If you would like to purchase the instructions to build it, you can do so by following this link.

MOC – Winterfell Castle – Game of Thrones

The next castle is a recreation of Winterfell, the house of the Stark family in Game of Thrones. The designer, ZeRadman, has done an extraordinary job with this design.

Containing 1799 parts, we think this set could easily be an official LEGO design due to its high quality. If you want to have a closer look at it and purchase the instructions, be sure to click on this link.

MOC – Rock Castle

The Rock Castle, from Lucky-Ramses, is clearly inspired by Minas Tirith from the Lord of the Rings. This MOC is based on the original LEGO 8781: Castle of Morcia. The improvement and the fact that the designer managed to make it look so similar to Minas Tirith is a great achievement.

The instructions for this specific MOC are free to download by following this link. There, you will also be able to get a bit more information about this specific MOC.

MOC – Sleeping Beauty Castle

The Sleeping Beauty Castle is a bit different from the other creations we have listed here. This one is much smaller, with only 398 pieces, but it is in any case difficult to build. The creator, benbuildslego, recommends it only for children over 12 years old.

We really like the look of it and we think it is one of the coolest from the set. If you want more information about this MOC or you want to buy the instructions, you can do so by following this link.

MOC – Hogwarts’ Castle Epic Extension

We started with Hogwarts and we will end up with Hogwarts. This is, by far, the coolest castle plan of all. It is also, by far, the most complicated to build. If you thought that the Hogwarts Castle set was huge with 6,020 pieces, get ready for this. This epic extension has a total of 19,307 parts, and that is without including the original pieces. Yes, I have not made a mistake there. If you add them up, the final castle would have a total of 25,327 pieces.

But the results are as astonishing. This castle is huge, measuring over 130.6 cm (51.4 in) wide, 93.7 cm (36.9 in) long, and 62.8 cm (24.7 in) high. But also the instructions are huge. The set of instructions goes over 3,000 pages.

The design was done by Ryan Kroboth, and Playwell Bricks created the instructions and made them available. If you would like to see a bit more information about the coolest castle plan or maybe purchase the instructions, you can do so by clicking here.

Final words

And with this epic castle, we have arrived at the end of this post.
