“With 3,395 carefully crafted pieces, this set beautifully captures the charm of an ancient fortress that has been overtaken by nature, yet reclaimed by the valiant Forestmen. Featuring 12 detailed minifigures, this set has no stickers, ensuring that every detail is... More brick-built, highlighting the intricate design of the abandoned stronghold. From the overgrown trees wrapping around the fortress to the worn cracks in the structure, it radiates character and history.”

“If LEGO never does a Forestmen-focused set ever again, you’ll definitely want to add this to your collection, and I’m glad that vehicles like the Bricklink Designer Program enables sets like this and the Castle in the Forest to become a reality.”

Oh no! The Black Falcon Knights have stumbled into a trap!

Deep in Ogel forest, sits an abandoned castle. Or so that’s what the local kingdoms believed! But a band of Forestmen have reclaimed this old fortress as their new home! Even though trees have started grow all around the old structure and cracks have begun to appear, the Forestmen don’t mind.

About this model
This castle comprises of two main sections with both containing many different rooms and details. The left portion comprises of a grand bedroom, large watch tower, and a hidden underground treasure room! The right side has a dining hall, armory, kitchen, tower dungeon, and more. These sections are connected by a small bridge.
All levels are accessible by minifigures via ladders and doors throughout the castle.
The bridge can be easily removed so that both castle sections may be easily transported. The separation could also allow for someone to pretend that they are controlled by different clans too!
