Admiralty House (Maltese: id-Dar tal-Ammirall), 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 houses were later leased to various owners, including Fra Raimondo de Sousa y Silva, who rebuilt them a single residence between 1761 and 1763.
