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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
