Immersed among the olive trees, Trevi stands on the slopes of Monte Serano.

Known in Roman times as Trebia, the town still bears witness to that distant era with the ancient fortified walls which date back to the first century AD.

Proceeding to the highest point in the town, you can find imposing building that testify the town's medieval history: Palazzo Valenti with its portal that displays powerful sculpted heads, Palazzo Natalucci with its arabic doors, and Palazzo Benedetti Valenti, which displays ancient archeological finds from around Umbria.

The Palazzo Comunale located alongside the tower has a beautiful loggia which is worth visiting.
