The Abbey of Santa Maria di Rovegnano, Chiaravalle Milanese (Latin: Sanctæ Mariæ Clarævallis Mediolanensis) is a Cistercian monastic complex in the comune of Milan, Lombardy, northern Italy. The borgo that has developed round the abbey was once an independent commune called Chiaravalle Milanese. This is now is included in Milan. The abbey was founded on 22 January 1135 as a daughterhouse of Clairvaux; it is one of the first examples of Gothic architecture in Italy, although maintaining some late Romanesque influences.
