Located at the entrance to the square of the same name on Corso Umberto I, it has a rather modest stone portal and extends along Via Duca degli Abruzzi with a single nave.

It was probably built at the end of the 17th century and it is thought that its name refers to its position on the ridge, which at that time was steeply sloping to the north-east.

There are various hypotheses, none of which has been documented, about the steeply sloping roof, which is reminiscent of mountain dwellings.

Directly in front of the entrance, at a distance of no more than thirty metres, is the church of San Leonardo, destroyed by the earthquake of 1783, while the church of Santa Maria was damaged by the earthquake of 1908 and quickly repaired. Presumably spared by the earthquake, the interior preserves a beautiful painting depicting Saint Leonard, invoked against Turkish raids.
