The castle was designed to be completely modular. It consists of 28 baseplate modules (A1 - G4) and 23 building modules (H01-H23). Each building is built separately and all floors are modularly removable and also have an interior. The real model houses over 325 minifigures, but I have left them out here.
The palace area, the right part of the castle, has a complete basement. A side entrance (G1) leads through a corridor (F1) to the torture chamber (E1). The prison building (H06) is connected to the torture chamber. In the corridor there is another branch that leads to a small antechamber (G2 & F2). After that there is a large storage room (G3 & F3). From this room you have access to the mine, where gold can be mined (F2). From the storage room you can also access the treasure chamber (E3) via a secret door. A staircase in the storeroom then leads to the palace courtyard directly in front of the door to the palace kitchen.
