Porta Soprana o Urbica di Sant'Andrea

The city of Genoa during its long history at least since 9th century had been defended by different line of walls. To this day, large portions of these walls remain, and Genoa has more and longer walls than any other city in Italy. The main city walls are known as “Ninth century walls”, "Barbarossa Walls" (12th century), "Fourteenth century walls", "Sixteenth century walls" and "New Walls" ("Mura Nuove" in Italian), the more imposing, built in the first half of 17th century on the ridge of hills around the city, having a length of almost 20 km (12 mi). Some fortresses stand along the perimeter of the "New Walls" or close them.
