the most important place in Amalfi Coast

It is a 9th-century Roman Catholic structure in the Piazza del Duomo, Amalfi, Italy. It is dedicated to the Apostle Saint Andrew. There were two churches on this site in Amalfi since 596 AD and the one built in the 9th century still stands today. It has been remodeled several times, adding Romanesque, Byzantine, Gothic, and Baroque elements.
The interior of the church is sumptuously Baroque but the underlying architecture is Romanesque. The High Altar in the central nave is formed from the sarcophagus of the Archbishop Pietro Capuano which is decorated with fine bas-reliefs of the Twelve Apostles with St. Basil, St. Nicholas, Jesus and the Virgin Mary. Niches in the right aisle display a large reliquary bust of St. Andrew (16th century) and the Coffin of the Dead Christ, which is carried in solemn procession through Amalfi on Good Friday.
