Duomo
This Gothic cathedral was built in the late 13th century. It is sumptuously decorated inside with frescoes and even the mosaic floor is a marvel to behold. There are crypts, anti rooms and a museum to explore as well as an ancient baptistry built in the first century.
The Dome which is known as the Capella di San Gennaro is stunning and is adorned with frescos from the 17th Century.
