The Battle of Preveza was a psychological boost for the Ottoman navy and allowed Barbarossa to capture almost all the remaining Venetian outposts in the Ionian and Aegean Seas. Since 1908 the date of the battle is celebrated as Navy Day in Turkey. The “Preveze” submarine class consists of four conventional submarines built in Germany. Hayreddin Barbarossa is considered a national hero and the Istanbul Naval Museum exhibits the 1866 painting “The Battle of Preveza” by Ohannes Umed Behzad.
