The 14th century Castillo de Bellver just outside Palma de Mallorca, Spain, is one of the few circular castles in Europe. Originally a residence of the medieval kings of Mallorca, it was later used as a military prison right up until the mid 20 century. #CastillodeBellver #PalmadeMallorca #Spain #Mallorca
