Santuario Basilica S. Valentino

The Basilica of St. Valentine underwent several reconstructions over the years. The first building dates back to the fourth century, and was built above the tomb of the martyr San Valentino, at an ancient early Christian necropolis. The current building, however, dates back to the 17th century, when under the pontificate of Paul V, the research of the relics of the saint was successfully started in the place where the first churches stood.
