LEGO 10305 Lion Knights' Castle is an Icons Castle set released in 2022, containing 4514 pieces and 22 minifigures. It builds a large medieval stronghold with a working drawbridge and portcullis, hidden passages and secret hideouts, movable walls, towers and turrets, a mill with a waterwheel, living quarters, and an armory. Developed to mark the LEGO Group’s 90th anniversary, the set was revealed at LEGO CON 2022 following a fan vote to revisit a classic theme. The design references earlier Castle-era models in its architecture and functions, with an instruction booklet insert highlighting historic LEGO castles.
