<em>This Primatial Abbey of the Benedictine Confederation was built at the behest of Pope Leo XIII as part of his project to unify the Benedictine order.</em>
At the end of the day on November 11, 2025, Leo XIV visited the Benedictine church of St. Anselm on the Aventine Hill in Rome, where he celebrated Mass for the 125th anniversary of the building's dedication.
By participating in this anniversary, the Pope honored his predecessor Leo XIII, whose name he took. That Italian pontiff, who ushered in the 20th century, promoted the construction of this church and brought the Benedictine monks together in a confederation.
