Amalfi's Cathedral of St. Andrew the Apostle is said to house the tomb of the Patron Saint of Scotland. Its construction began in the 9th century and is a combination of Moorish and Norman architecture. Its main attraction is a bronze door given to the citizens of Amalfi in 1066 by former Amalfitan, Pantaleone di Mauro Comite, who made his fortune as a pioneer merchant, settling in Constantinople (Istanbul).
