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. Goethe declared the view from the castle's position above the Elbe to be the most beautiful in Central Europe, while Richard Wagner's opera Tannhäuser was supposedly inspired by his visit to Strěkov. The castle was confiscated by the Nazi regime and later the Communist government, but was restituted to the Lobkowicz family in the early 1990s.
Střekov Castle is divided into two sections connected by an arched bridge spanning a natural moat— an unusual style for the 14th century, when it was first built. The castle’s semiround bastions, inspired by French architecture, are possibly the first example of that type of defensive design in Bohemia. The connecting round tower, a smaller tower guarding the castle entrance, and an irregular oblong section of the castle date back to the very earliest period of construction.References:
Narikala is an ancient fortress overlooking Tbilisi, the capital of Georgia, and the Kura River. The fortress consists of two walled sections on a steep hill between the sulphur baths and the botanical gardens of Tbilisi. On the lower court there is the recently restored St Nicholas church. Newly built in 1996–1997, it replaces the original 13th-century church that was destroyed in a fire. The new church is of 'prescribed cross' type, having doors on three sides. The internal part of the church is decorated with the frescos showing scenes both from the Bible and history of Georgia.
The fortress was established in the 4th century and it was a Persian citadel. It was considerably expanded by the Umayyads in the 7th century and later, by king David the Builder (1089–1125). Most of extant fortifications date from the 16th and 17th centuries. In 1827, parts of the fortress were damaged by an earthquake and demolished.
