The blog link mentioned below is worth taking a look at. Well written and presented with a few pictures from inside the monastery.
The Holy Father began the holy season of Lent by going to the Church of Saint Anselm (Benedictines) atop the Aventine Hill. After a brief prayer, the Bishop of Rome led the congregation in procession to the Basilica of Saint Sabina (Dominicans) for Mass. In his homily Pope Benedict explained how, by following Christ on the path of humility, we can enter into the “‘greater’ justice, which is the justice of love.” The preliminary event was photographed and blogged by a student in one of the Roman universities.
