Teramo is situated near the confluence of the Vezzole torrent with the Tordino River (that's why the Latin name of Interamnia, between rivers), and is a very old city, founded in pre-Roman time, though the general aspect is more recent, due to many XIX-XX century buildings. Since for a long time it was a border place between the Kingdom of the Two Sicilies and the Church State, it acquired a really special identity and, because of the difficult communications with the other parts of the country, it stayed isolated for long periods of time.
