Sant'Anselmo, named after the Italian saint and theologian, Anselm of Canterbury, is the home of the Abbot Primate of the Benedictines, seat of the Benedictine Confederation, and also hosts an Athenaeum, including the Pontifical Liturgical Institute, and the Philosophy and Theology faculties. Located on the Aventine Hill in Rome, Italy, Sant'Anselmo is a beautiful 19th century monastery, built in a classical style, on top of Roman ruins which date from the 1st century BC to the 4th century AD. These remains are visible and visitable, by arrangement, under both the first courtyard and in the basement.
