Fort Vrmac is a former fortification of the Austro-Hungarian Empire located on the southern end of the Vrmac ridge near Tivat. Established in 1860, the present structure was built between 1894 and 1897, and saw action during the First World War, when it was heavily bombarded by the Montenegrins. It was repaired and disarmed before the end of the war and was abandoned after a period of occupation by Yugoslav troops. Today it is one of the best preserved Austro-Hungarian fortifications in the Bay of Kotor area.
The fort comprises a heavily reinforced stone and concrete structure situated within a ditch, defended by three caponiers. There is a single entrance on the north side, accessed from the ditch and protected by a caponier. The design is similar to that of the 'Vogl period' fortresses in South Tyrol, with an irregular pentagonal shape constructed on two levels. The main guns were housed in armoured casemates, with howitzers and observation turrets in steel cupolas made by Škoda in Pilsen.
The roof of the fort is a 1.5 m thick slab of concrete that was installed in 1906–1907 following improvements to Montenegrin artillery capabilities. The barracks rooms are located on the ground and first floors on the north side while the casemates are situated on the other sides of the fort, facing towards what was then potentially hostile territory. A separate structure a short distance to the north of the fort was used as an ammunition magazine.
References:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
