Castle

Castles are a recurring type of locations found throughout the Final Fantasy series. Castles are very versatile in their appearances, and can be both hostile and abandonend or of friendly alignment. They are usually accessed via World Map, and in case of being friendly, are usually located near Towns, or may be even Citadels.

It is noteworthy that, starting with Final Fantasy VII the appearance of castles in the series has become scarcer.
