The round hilltop castle built in 1309 was the summer residence of the kings of Mallorca during the short period in which the island had a Royal family. The fortified castle with its double moat also served as a prison. Today, it contains Palma's Municipal Museum, displaying mainly archaeological artefacts and old coins. There are also models of archaeological digs to be seen.
