Sant'Anselmo all'Aventino (Italian:St Anselm on the Aventine) is a Roman Catholic church, monastery and college located on Cavalieri di Malta Square on the Aventine Hill in Rome's Ripa rione. It is named in honor of Saint Anselm of Canterbury.
The buildings were designed by Hildebrand de Hemptinne and Fidelis von Stotzingen and built in 1900. The International College of Sant' Anselmo is located here, as is the seat of the Abbot Primate of the Federation of the 'Black Monks' (which includes all monks under the Rule of St Benedict except the Cistercians and the Trappists). The attached abbey is called Badia Primaziale (Primatial Abbey) of the Order of Saint Benedict. The complex also hosts the Pontificio Ateneo Sant Anselmo, including the Pontifical Liturgical Institute, and the Philosophy and Theology faculties.
The church has a basilical plan, and its mosaics have only the figures in mosaic and no background. The paschal candlestick is modern but in the Cosmatesque style. The crypt can be visited, through a door by the altar of the Blessed Sacrament. Behind this altar is a statue of St Benedict, with his arms raised in prayer - the posture in which he died.
