A whole series of disasters struck the castle of Saint Andrew in the 20th century. The eastern walls (towards the sea) were demolished in the late 19th century to make room for upscale mansions. When the Greek army liberated Preveza (1912), they expanded the barracks and turned the mosque into an archaeological museum. It was destroyed during a bombardment by the Italians in 1940. In September 1944, communist guerrilla fighters captured the fort and fought against their right-wing opponents, who used mortars in an effort to dislocate them. The castle housed the Greek army until 2000 but is now semi-abandoned. The monument to the people of Preveza who lost their lives in the conflicts of the last century bears testament to the region’s turbulent past.
