Its foundation goes back to the Romans (his coat of arms bears the inscription Descendit former patribus Romanorum). From the ninth century, the first (in chronological order) between the maritime republics, rivaled Pisa, Venice and Genoa for control of the Mediterranean Sea. The Maritime Code of Amalfi, better known as Tables of Amalfi, had a great influence until the seventeenth century. Amalfi reached its maximum splendor in the XI century, then began a rapid decline: in 1131 it was conquered by the Normans in 1135 and 1137 and sacked by Pisa. In 1343, then, a storm resulting tsunami destroyed much of the city.
The most famous monument of Amalfi is certainly the Duomo in Arab-Sicilian style and currently dedicated to Saint Andrew, the patron saint of the city.
