The Burgkirche ('castle church') is one of the largest and most imposing fortified churches in western Germany. The church is surrounded by a cemetery, which is surrounded by walls. The Romanesque tower of the church with Gothic battlements and turrets is the oldest part of the church, which was built in several phases in the late Gothic period. The restored stained glass windows and paintings in vaults - both from the 15th century - are worth of seeing. The church served as a graveyard of local nobility and has lots of interesting tombs.
References: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.
