The Tower of Botsaris lies close to the Venetian Castle and the port of Nafpaktos. It is an impressive construction, which actually consists of two towers. The first tower, the west one, was built in the 15th century by Venetian builders. The east tower was built in the 16th century by the Turks. This construction was firstly used as a residence for the Turkish governors of Nafpaktos. 
After the liberation of the city (18th April 1829), this tower was bought by general Notis Botsaris, member of Botsaris family from Souli, Epirus, who contributed a lot to the Greek War of Independence. The tower belongs today to the Dimitrios and Egli Botsaris Institution and works as a museum. The ground of the tower hosts a permanent exhibition about the Battle of Lepanto (October 1571). The exhibition constitutes of 80 replicas of paintings and gravures, made by the most famous artists of that era. Source: www.greeka.com
