The Castell de Sant Carles on the outskirts of Palma de Mallorca was built in the 17th century opposite Porto Pi as a fortification to defend the town’s port. Nowadays, the fortress is open to the public in its capacity as the Museu Històric Militar de les Balears (Military Museum). I found my visit there a few weeks ago very worthwhile, and I am not a military person whatsoever.
The precinct of Sant Carles and the museum can be visited from Monday to Friday (09h00 to 13h00) and Saturdays (10h00 to 13h00). Both are closed Sundays and on public holidays. The admission is free.
