Konopiste Castle is a former royal chateau located in the Czech Republic, about 44 km southeast of Prague. The castle was originally built in the 13th century as a Gothic fortress, but underwent numerous renovations throughout the centuries, including a significant reconstruction in the late 19th century by its owner, Archduke Franz Ferdinand d'Este.

The castle is known for its stunning architecture and interiors, featuring a unique combination of medieval and modern styles. The castle's collections include a vast assortment of art, historical weapons, armor, tapestries, porcelain, and other decorative objects.

Konopiste Castle is also famous for its association with Archduke Franz Ferdinand, who lived there for many years and filled the castle with his extensive collections. He was assassinated in Sarajevo in 1914, an event that led to the outbreak of World War I.

Today, the castle is open to the public and visitors can explore the castle's many rooms, including the hunting salon, smoking room, and armory. The extensive gardens surrounding the castle are also open to visitors, offering picturesque views of the surrounding countryside.
