Fort Gorazda was built by the Austro-Hungarian Empire near Kotor. The fortress's predecessor was built prior to the 1869 uprising. The current fort was built between 1884–86 and replaced an earlier structure; its most notable feature is a 100-ton Gruson rotating turret on its roof, the last remaining example of its type. The fort was used by the Austrians in artillery duels against Montenegrin batteries stationed on Mount Lovćen during the First World War. The Montenegrins were unable to destroy it and were pushed out of range in 1916 by an Austrian offensive. The damage to the fort was repaired and its guns were removed to support the Austrian field army. It was used as a depot by the Yugoslav Army until as recently as the early 1990s. It was subsequently abandoned and can be visited by the public.
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.
