Schreckenstein Castle or, less commonly, Strekov Castle, is a well preserved ruined castle perched atop a cliff above the River Elbe near the town of Ústí nad Labem in the Central Bohemian Highlands in Czechia. It was built in the 14th century to protect the waterway and collect duties on transported goods, the castle is renowned for its impressive views. It has enchanted a variety of visiting artists, most notably Goethe, Richard Wagner, and Karel Hynek Mácha.
The castle is especially well known from the painting by Ludwig Richter called Passing the Schreckenstein which hangs in the Galerie Neue Meister in Dresden.
