Museo Arqueolóxico e Histórico, Archaeological museum in Castillo de San Antón, A Coruña, Spain

The Museo Arqueolóxico e Histórico occupies Castillo de San Antón, a 16th-century fortress sitting directly on the coast overlooking the bay. The building houses artifacts spanning different time periods alongside medieval objects and materials documenting regional events.

Construction of the fortress on the island of San Antón began in 1588 as a defence against attacks by sea. It later served as a military and political prison until well into the Franco dictatorship. In 1949 it was declared a historical-artistic monument, and in 1960 the Ministry of Defence ceded it to the city council, which approved its conversion into a provincial archaeological museum in 1964. After consolidation work by the architect Pons Sorolla, it opened to the public on 5 October 1968 under director José María Luengo Martínez.

The collections highlight the role of the fortress in local life and regional identity through objects and displays connected to A Coruña's past. Visitors can observe how the space preserves memories important to the community.

The museum sits right on the waterfront and is easy to reach from the city center with clear signage along the way. Plan for about two hours to explore the exhibits comfortably.

In the castle chapel, two side murals painted by Xosé Sesto in 1982 flank the Virgen del Rosario: one shows the Apotheosis of Saint Anthony with his temptations and miracles, the other the illustrious prisoners held in the fortress, gathered around the Virgin.
