Porto Pisano, also known as Triturrita,[1] was the main seaport of the Republic of Pisa, located on the Ligurian Sea coast close to the mouth of the Arno River.
In the 13th century, at its peak, Porto Pisano was one of the most important sea ports in Italy, which rivaled if not surpassed both Genoa and Venice.
[2] In the Battle of Meloria in 1284 Porto Pisano was blockaded by the Genoese fleet, and Pisa suffered a heavy defeat, which eventually resulted in its decline.
In the 12th century, Pisa was one of the most important trading cities of Italy, however, it was located slightly off the coast and badly needed a sea port.
This short stretch of the coast was under constant threat by the Genoese and by pirates, and therefore needed to be patrolled by the Pisan fleet.
