On 12 August 1955, the lease to the Malta Union Club was terminated.  In 1958 the auberge was opened as the National Museum, housing the Archaeological Collection on the ground floor and Fine Arts on the first floor. In 1974, the Fine Arts collection was transferred to Admiral House and the auberge became the National Museum of Archaeology. The auberge is listed on the National Inventory of the Cultural Property of the Maltese Islands.
