Admiralty House (Maltese: id-Dar tal-Ammirall),[1] formerly known as Casa Miari, Palazzo Don Raimondo and by several other names, is a palace in Valletta, Malta.

It was originally built in 1569–70 as two private houses by Fra Jean de Soubiran dit Arafat, a knight of the Order of St. John.

The properties passed down to another knight François le Petit de la Guerche, and were taken over by the Treasury of the Order of St. John upon his death in 1663.

[3] During the French occupation of Malta, the government offered the building to Bishop Vincenzo Labini as a seminary, but these plans were never implemented due to the Maltese uprising and blockade of 1798–1800.

[8] The building received various notable personalities as residents or guests, including Lord Mountbatten, Winston Churchill, King George V and Queen Elizabeth.

[13] In November, of that year, it was concluded that further development of the buildings would not be appropriate and the three joined houses are not adequate to host the entire ministry with its necessities and to accommodate roughly 200 people as working staff.

[13] The façade was originally decorated with escutcheons containing the coats of arms of the Order and of Grand Master Manuel Pinto da Fonseca, but these were defaced during the French occupation of 1798–1800.

[8][10][17] It might have been influenced by the staircases at Auberge de Castille in Valletta, Würzburg Residence in Bavaria and Palais Kinsky and the Upper Belvedere in Vienna.
