The Tower of San Floriano is a military construction located in the homonymous hamlet of Vittorio Veneto, in the heart of Val Lapisina. It stands on a hill of artificial origin, on the southern shores of Lake Restello. Tradition dates it back to Roman times, but its appearance is undoubtedly medieval. It is a watchtower which had the task of monitoring the important road that led to Cadore and from there to Tyrol and Germany. It is likely that it also had customs functions.
