The Certosa di Trisulti (English: Trisulti Charterhouse) is a monastery in Collepardo, province of Frosinone, central Italy. It is located on the slopes of Monte Rotonaria, a peak of the Monti Ernici, at 825 meters above the sea level. It was consecrated in 1211, becoming a national monument in 1873.
A first Benedictine abbey was founded in the site in 996 by St. Dominic Abbot: some remains can be seen today not far from the current building. The latter was erected starting from 1204, on a more accessible location, by will of Pope Innocent III, who assigned it to the Carthusians. The abbey church, dedicated to St. Bartholomew, was consecrated in 1211.
The name Trisulti could derive from Latin tres saltibus, meaning "At the three jumps": this was the name of a castle of the baronal Colonna family which commanded the three passes ("jumps") leading to Abruzzo, Rome and Ciociaria.
The complex was enlarged and modified several times in the following centuries. The current appearance date to an essentially Baroque restoration.
