Embedded in concrete outside the museum entrance is the warship Druzki , which torpedoed a Turkish cruiser during the First Balkan War in 1912. It’s possible to clamber around this revered relic (ask the museum staff to open the gate). Inside the musty museum building itself is a collection of uniforms, model ships, naval insignia and displays on the Druzki, including an enormous torpedo, although there’s little labelling in English. Anchors, artillery and helicopters can be seen rusting quietly in the grounds, while encased in glass is the yacht Cor Coroli, in which Georgi Georgiev became the first Bulgarian to sail single-handed around the world, in 1977.
