LEGO SET 10305 - Alternate build | Lion Knights' Castle
The Lion Knights’ Castle (set 10305-1) is more than an iconic display piece—it’s a treasure chest of slopes, arches and golden accents just waiting to be reborn. By reusing only the elements in the original set, builders have transformed this regal fortress into outposts, world-spanning villages and even Middle-earth strongholds. Whether you’re chasing new display ideas or seeking clever ways to squeeze every ounce of play value from your bricks, these MOCs offer a wealth of inspiration .
From small watchtowers to fully configurable castle worlds, each designer’s creation showcases unique techniques for repurposing walls, turrets and lion-emblazoned flags. You’ll find clever part swaps that turn battlements into lighthouse beams, modular extensions that expand the realm, and atmospheric builds that evoke medieval shires and epic battles. Dive in, pick your favorite, and discover how a single set can fuel dozens of new adventures.
