Ratibořice, Empire style château in Česká Skalice, Czech Republic

Ratibořice Château is a Baroque hunting lodge built by Lorenzo Piccolomini between 1702 and 1708, later rebuilt in Empire style for Duchess Katharina Wilhelmine of Sagan in 1810–1812. Architect Andreas Tetílek of Hohenmauth designed the original Italianate villa; only the perimeter walls of the Baroque structure survive, with a long single-storey service wing added in the 18th century.

The property began as a medieval farmstead and was transformed in the early 1700s when Lorenzo Piccolomini built a Baroque palace on the site. This shift marked the transition from rural land to an aristocratic residence.

Božena Němcová spent her childhood in Ratibořice, and her novel Babička made the château and the Úpa valley famous; the character of the princess has as her model Duchess Kateřina Vilemína Zaháňská, who used the château as her summer residence. The nearby Staré Bělidlo (Old Bleachworks) and the Babiččino údolí valley are part of the novel's setting.

The château stands above the Úpa valley north of Česká Skalice, reached on foot from the village along paths through the Babiččino údolí national nature reserve. The interiors are shown on guided tours, while the grounds and the Staré Bělidlo (Old Bleach-house) can be seen independently. The building is a national cultural monument administered by the National Heritage Institute.

In June 1813, Russian Tsar Alexander I and Austrian Chancellor Metternich met here to discuss military strategies against Napoleon. This diplomatic moment ties the building to major political events of the early 19th century.
