Salerno Cathedral (or duomo) is the main church in the city of Salerno in southern Italy and a major tourist attraction. It is dedicated to Saint Matthew, whose relics are inside the crypt. Begun by Robert Guiscard in 1076 in the episcopate of Alfano I, the Duomo was consecrated by Pope Gregory VII in 1084.
The Duomo is a symbol of the Italian Renaissance because inside is the tomb of Pope Gregory VII who rejected imperial domination of the church.
