The Auberge de Provence was built between 1571-75 to a design by the Maltese architect Girolamo Cassar. The façade was re-designed during the first half of the 18th century. The Auberge was the residence of the Langue de Provence, its Head, the “Gran Commandeur” being the Treasurer of the Order.

From 1824 to 1954 the building housed the British officers’ Union Club, and is now the National Museum of Archeology.
