Tullus Hostilius is said to have destroyed Alba Longa.

Alba longa.

Alba longa is slightly farther north than rome. it too is on the tiber river. Alba longa is said to the birthplace of romes founder Romulus and his brother Remus.

It is not sure where Alba Longa was, as it is a 'lost' town. The most likely guess is Castel Gandolfo, 15 miles SE of Rome. Alba Longa was associated with the Alban Hills, the original heartland of Latium, and was said to be at the foot of the sacred Mons Albanus (today's Monte Cavo). It is thought that it was on the western shore of lake Albano. Cemeteries of several proto-urban centres have been found along this shore and Castel Gandolfo had the largest one, suggesting that it was the nucleus of the area.
