At a height of 100 meters above the Elbe, a monolithic rocky cliff towers above the castle ruins of Střekov, also known as Schreckenstein, which became famous thanks to Ludwig Richter's painting “Die Überfahrt am Schreckenstein”, which is currently on display at the Galerie Neue Meister in Dresden's Albertinum. The first documented mention of the Schreckenstein dates back to 1319, when Pesek von Střekov received the castle as a fief, and at the beginning of the 16th century, the Schreckenstein changed hands several times until Wenzel Popel von Lobkowitz took over the castle in 1563. Further alterations and extensions were made around 1570. In the 19th century, the picturesque castle complex became an excursion destination for the first travelers, including famous painters such as Ludwig Richter and Caspar David Friedrich. In 1842, the composer Richard Wagner visited Schreckenstein and was inspired to write his opera Tannhäuser. Large parts of the castle have been preserved or reconstructed to this day, such as the keep, the palas and the curtain walls.
