This museum on the history of Ciutadella and Minorca in general covers the time from prehistory to the Moorish period. Because all the archaeological finds recovered from excavations in the city are deposited there, it contains invaluable collections from the prehistory, ancient history and medieval history of the city (such as pieces from the caves of es Carritx and es Mussol).
It features a permanent collection that begins with the first settlements on the island and ends with material from the Moorish period. It also organises temporary exhibits on many different subjects (such as the pieces found at the underwater excavation in Cala en Busquets). The basic aim is to give a broad range of public an appreciation for the island's different lifestyles, customs and cultural heritage. This is very much a local museum, owned and managed by the city.
It is located inside one of the bastions of the Renaissance city walls of Ciutadella, called the Bastió de sa Font, which was built (1677-1692) to protect one of the entrance gates of the impressive medieval walls surrounding the city. It is listed as a Bien de Interés Cultural.
