“This castle is debatably the finest ever released by LEGO, even though the raised plate is disapproved by some, it is still one of the most interesting, largest and coolest looking castles around. I think this is one of the best castles TLG has ever produced, the design is... More just incredible and it makes the set look so unique.”

“I think this is one of the best castles TLG has ever produced, cause though it has a raised baseplate, it got an incredible design that makes it look unique. There are plenty of figs coming with it what is great, but also every fig is different. Add lots of accessoires, rare... More pieces and great playability, this set is totally perfect.”

“Black Knight's Castle was released in 1992. This castle has a main gate tower with a drawbridge and portcullis. There are two diagonally symmetrical corner archer towers. One has a jail. The last corner is made of yellow "tudor" wall pieces and has a side entrance. Four... More mounted knights, four archers, two soldiers, one wolfpack prisoner, one ghost, and various accessories are included.”
