“It’s the build adult LEGO® fans have been waiting for. A classic – reimagined. Celebrating 90 years of LEGO history, the Lion Knights’ Castle is a new interpretation of the iconic LEGO Castle theme. The impressive set is packed with details, and with 4,514 pieces it offers a... More project to savor. So, rekindle your childhood joy as you uncover the many stories and surprises packed into this model.”
Brick Fanatics
“Several castles in the Castle theme had hinged sections integrated into their walls. This allowed them to be displayed as an enclosed structure or mimic the walls of a much larger building instead. 10305 Lion Knights’ Castle retains that feature, which – given the level of... More detail in it – is perhaps to be expected. As such, you can display the set in one of two configurations depending on your preference. However, the set reportedly measures 38cm high, 44cm wide and 33cm deep when it’s folded up. From that perspective, displaying it open may prove a challenge of its own.”

With an amazing array of minifigures, beautiful external and internal details and the nostalgic factor this set will blow any builder away. Not only is this set a terrific... More display piece but it also comes packed with design details that makes the build process of this set varied and fun.”
