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.
Střekov Castle (Schreckenstein) is perched atop a cliff above the River Elbe, near the city of Ústí nad Labem. It was built in 1316 for John of Luxembourg, the father of the Holy Roman Emperor Charles IV, to guard an important trade route to Germany. After changing hands several times, the castle was acquired by the Lobkowicz family in 1563. Its strategic importance led to occupations by Imperial Habsburg, Saxon, and Swedish forces during the Thirty Years' War, as well as successive sieges by Austrian and Prussian armies during the Seven Years' War.
Although Střekov Castle was heavily damaged during those conflicts and abandoned as a military installation by the end of the 18th century, the 1800s saw many poets and artists visiting the castle, drawn by a new trend of interest in romantic ruins.
