At a height of 100 meters above the Elbe rises a monolithic cliff on which the castle ruins of Střekov, also known as Schreckenstein, are enthroned.Střekov gained fame through the painting “The Crossing at Schreckenstein” by Ludwig Richter, which is currently on display in 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 renovations and extensions were carried out around 1570. In the 19th century, the picturesque castle complex became a popular destination for travelers, including famous painters such as Ludwig Richter and Caspar David Friedrich. The composer Richard Wagner visited Schreckenstein in 1842 and drew inspiration for his opera Tannhäuser. Large parts of the castle have been preserved or rebuilt to this day, such as the keep, the palas and the castle walls.
