Bellver Castle is a Gothic-style castle on a hill 3 km to the center of Palma.It got built in the 14th century for King James II of Majorca, and is one of the few circular castles in Europe. First serving as the residence of the Kings of Majorca, and afterward long used as a military prison throughout the 18th to mid-20th century, it is now under civilian control, being one of the main tourist attractions of the island, as well as the seat for the city's History Museum.
The main part of the fortification was built by architect Pere Salvà, who also worked in the construction of the Royal Palace of La Almudaina, together with other master masons between 1300 and 1311 for King James II of Aragon and Majorca. Rock from the hill where the castle sits was used for the building, which has eventually led to the appearance of cracks. Once the castle had been built, and following the introduction of artillery, the battlements on the top balconies and the barbican disappeared, being soon followed by those in every tower; loopholes were built instead.
The castle has only fallen once in its history into enemy hands, in 1521 after an assault during the Majorcan second Revolt of the Brotherhoods.When we where there for a visit, there was an marriage ongoing into the castle, seems to be normal that those things happen.
