10 Inspiring Game of Thrones Castle LEGO MOCs: Instructions, Tips and Ideas

LEGO Game of Thrones Castle MOCs – Build the Seven Kingdoms in Bricks

From the basalt cliffs of Dragonstone to the sprawling courtyards of Winterfell and the sun-baked spires of the Red Keep, the castles of Westeros are practically made for LEGO. They’re moody, modular, and packed with recognizable silhouettes—perfect for translating into studs, slopes, and arches. A great Game of Thrones castle MOC starts by choosing a scale: minifig-scale for immersive play and interior details, or micro/skyline scale for sweeping geography and a satisfying, display-friendly footprint. Once the scale is set, lock in a color story. For Northern strongholds, mix light bluish gray with dark bluish gray and patches of white to suggest snowdrifts; for King’s Landing, lean into tan, dark tan, and warm accents; for Dragonstone, go dramatic with black and dark bluish gray rockwork punctuated by muted red banners.

Use SNOT and hinge techniques to angle walls and create tapering towers. Layer irregular rockwork with wedge plates and inverted slopes; break up long runs of masonry with buttresses, arrow slits (1×1 headlight bricks work wonders), and crenellations. Water is easy to stage with trans-clear over dark blue, while snowy courtyards pop with a scatter of white plates and curved slopes. Consider “book modularity”: build gatehouse, curtain wall, great hall, and keep as separate chunks that lock together—great for photography, transport, and upgrades. Finally, don’t forget storytelling: a dragon perch, a godswood sapling, wildfire catapults, or a tiny Night’s Watch ranging party turn a pretty model into a scene fans instantly recognize.

Tips for Building Game of Thrones Castles

• Start with silhouettes: block out towers, walls, and cliff lines in basic bricks before detailing.

• Mix textures: alternate masonry bricks, 1×2 grille tiles, and jumper-studded sections for “old vs. repaired” stone.

• Shape towers with facets: combine 1×2–2×2 brackets, 1×1 rounds, and hinge plates for near-circular drums.

• Rock foundations first: set a sturdy, irregular base; anchor walls into studs for strength at the cliff line.

• Use color subtly: tan/dark tan for King’s Landing; cool grays/white for the North; black/dark gray for Dragonstone.

• Add modular interiors (throne room, armory, maester’s study) that slide out for photos/play.

• Scene dressing: banners, braziers, ballistas, boats at Blackwater Bay, and—of course—dragons.

• Display smart: a narrow “skyline” base captures multiple landmarks with minimal parts.

Ideas for Types of GoT Castle MOCs

• Iconic fortress replicas: Red Keep, Winterfell, Dragonstone, the Eyrie, Castle Black.

• Battle dioramas: Blackwater Bay (ships + wildfire), the Battle of the Bastards (snowfields + palisades).

• Skyline series: stitch multiple seats of power into one elegant shelf-piece.

• Micro-geology studies: just a cliff + gatehouse or a godswood courtyard vignette.

• UCS-style centerpieces: multi-thousand-part show models with modular sections.

• Interior cutaways: throne rooms, crypts, maesters’ towers with removable walls.

• Wall cross-sections: Castle Black + The Wall with lifts, tunnels, and icy textures.
