What is the history of the Early Christian Basilica of San Lorenzo?
The Basilica was built in the 5th century AD as a funerary church. It had a Greek cross plan, with four apses and a dome at the center. In the surrounding area, there was a large necropolis where the city's first bishops were buried, such as Saint Gratus and Saint Agnellus. Over the centuries, the building was modified several times and partially destroyed. In the Carolingian era, the original structure was demolished and rebuilt in a simpler form. The current facade seen today dates back to the 17th century.
