A first
Benedictine abbey was founded in the site in 996 by
Saint 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 order of
Pope Innocent III, who assigned it to the Carthusians. The abbey church, dedicated to
Saint 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 baronial
Colonna family which commanded the three passes ("jumps") leading to
Abruzzo,
Rome and
Latium. The complex was enlarged and modified several times in the following centuries. The current appearance dates from an essentially
Baroque restoration. In 1947 the monastery was taken over by the Cistercian
Congregation of Casamari Abbey and continues as a Cistercian monastery. In 2018 the former White House Chief Strategist,
Steve Bannon, announced plans to establish a "gladiator school" for aspiring right-wing politicians in the charterhouse. The
Dignitatis Humanae Institute, founded by a European associate of Bannon's named Benjamin Harnwell, was evicted from the charterhouse by the Italian government after it was alleged that rent was not paid and Harnwell had obtained the lease fraudulently. In 2024, an Italian court ruled that the lease had been obtained correctly and all funds had been paid. ==Description==
