The Palermo Cathedral (also called Santa Maria Assunta or simply the Duomo) was begun in the late 12th century under Norman rule, and was expanded and renovated over the subsequent six centuries. Today, the imposing church is a striking mix of architectural elements, making it one of the most unique in Italy. The interior contains tombs of several members of the Sicilian royal family; the treasury’s collection of religious art, objects, and vestments; and the crypt with sarcophagi from the Roman era.
Because of its rich history and complex architecture, the Palermo Cathedral is best visited with a guide as part of a small-group or private tour. Most walking tours of the historic center of Palermo include a visit to the Cathedral along with other attractions like the Royal Palace and the Massimo Theater. Otherwise, you can join a hop-on-hop-off bus tour and explore the church and other sights independently.
