The cathedral was erected by Robert Guiscard and then consecrated in 1084 by Pope Gregory VII who had fled to Salerno to find rescue.
The atrium is surrounded by a portico supported by 28 raised arched columns. The main entrance to the Duomo has an impressive Byzantine bronze door set in a Romanesque marble portal flanked by two lions.
