Bled Castle stands on a cliff towering over Lake Bled. It was built in the early 11th century by the Bishops of Freising, and for centuries was the seat of the Bishopric of Gorenjska. In 1511 the castle was badly damaged by an earthquake. In the latter half of the 19th century Viktor Ruard, an industrialist and foundry owner, bought the castle and property, and the castle changed owners several times. Today it is public property run by the National Museum of Slovenia. The present look of the castle dates from the late 17th century and includes major restoration works carried out in the 1950s. Preserved from the original building are the Romanesque walls with an entrance tower and the reconstructed wooden defence corridors, while the other sections of the castle are generally in Gothic and Renaissance styles. The Castle Interior exhibition was prepared by the National Museum in 1957. It features furniture and art objects of a range of styles from Gothic, Renaissance and Baroque to Mannerism, Classicism, Biedermeier and Historicism. Within the castle rooms the history of Bled and Bled Castle is presented, alongside archaeological sites and finds from the environs of Bled.
