The Torre dello Standardo, a watch tower forming part of the city’s fortifications, was built by the Order of St John in the 16th Century and used to communicate signals between Mdina and the rest of Malta. It was also used to accommodate volunteers and servants of the sanatorium of the British army, as well as Mdina’s police office. Today, the tourist information centre is located in the tower.
It is of finer construction than other towers in Malta, having decorative Baroque elements such as mouldings, as well as escutcheons containing the coats of arms of De Vilhena and the city of Mdina.
