Certosa di Trisulti

Certosa di Trisulti is a Carthusian monastery in Collepardo set within an oak forest at 825 meters in the Ernici Mountains. Gothic arches alternate with Baroque stucco work, and several cloisters connect the monastery buildings together.

Pope Innocent III ordered the construction of the complex in 1204 on the site of an older monastery founded by Saint Dominic of Sora around the year 1000. Carthusians lived here for centuries until state interventions in the 19th century caused interruptions.

The name comes from the Latin tres saltus, referring to the three mountains or valleys surrounding the site. Carthusian monks once followed strict rules of silence, and visitors today still notice the quietness that fills the courtyards and walkways.

The monastery opens in summer from April through October daily between 10:00 and 13:30, then from 14:30 to 18:00. Winter hours shorten to 10:00 through 16:00.

The 18th-century pharmacy preserves containers for medicinal herbs and displays Pompeian paintings on walls and ceiling. Monks once produced liqueurs here, including one made from an old recipe still known today.
