Description
About this set
Two classic LEGO castles come back in micro scale here: the 6073 Knight’s Castle and the 6086 Black Knight’s Castle. Both have gates that flip up. The smaller one opens out into a fortress wall and hides a glow-in-the-dark ghost in one of its towers. You also build two tiny mounted knights, each dressed in their own castle’s colors.
Anyone who grew up with LEGO Castle sets will feel right at home with this 590-piece build. It’s a heritage set made with collectors in mind, and now that it’s retiring, sealed copies are only going to get harder to find.
Highlights
- Micro versions of the 6073 and 6086 castles
- Flip-up gates on both castles
- Glow-in-the-dark ghost in a tower
- Two micro knights on horseback
- Built from 590 pieces in total
