Drum Castle

Drum Castle (ドラム城) is a huge castle located on top of the largest mountain of the Drum Rockies on Drum Island. It first appeared in Chapter 132 and Episode 79.

Formerly inhabited by the royal family of Wapol and their servants, the castle is now owned by Dr. Kureha. Since Wapol left, the main entrance has been left open (because snow birds made a nest on top of the door), causing many rooms to freeze over. The armory contains many strong weapons, and in one of the towers is a powerful cannon, which no longer works properly, since birds also made a nest there, as well. It is also where Tony Tony Chopper lived, after the death of Hiluluk, until he left to become the doctor of the Straw Hat Pirates.
