Santa Maria in Trastevere (Italian: Basilica di Santa Maria in Trastevere) is a titular church and minor basilica located in Trastevere, Rome. Traditionally considered one of the oldest churches in the city dedicated to the Virgin Mary, it has served as a cardinal titular church since the 3rd century. The present basilica, largely rebuilt under Pope Innocent II in the 12th century, is renowned for its medieval mosaics, Baroque interior, and the Madonna delle Clemenza. Today, it remains a vibrant parish and a traditional site of pilgrimage, especially during Marian feasts such as the Assumption on 15 August.
