Castello Altemps

There are few historical references of the Altemps Castle, but on the basis of some documents, it is assumed that it was restored during the fifteenth century at the behest of Pope Alexander IV. The architect Antonio di San Gallo equipped the fortress with crenellated towers. Later it was transformed into a Palace at the behest of the nobles of the time and is currently the home of Luigi Hardouin and the Duke of Gallese.
