The Cathedral of St. Andrew, Amalfi is a highly unique cathedral full of interesting sights. Built in the early 1200s, the cathedral features a dramatic location atop a steep flight of stairs, an Arab-influenced exterior, and the relics of St. Andrew the Apostle in its crypt. Connected to the cathedral is an older basilica (now a small museum) and the fascinating Cloister of Paradise, both containing medieval murals. Dozens of reliquaries are displayed in the Chapel of the Relics (Chapel of the Reconciliation), some contain relics brought to Amalfi at the same time as those of St. Andrew.
