Zámek Třebnice

Sedlčany, Czech Republic (Czechia)

---

Zámek Třebnice is a castle located in the village of Třebnice near Sedlčany in the Central Bohemian Region of the Czech Republic. Originally built as a medieval fortress, it was extensively rebuilt in the Baroque style during the second half of the 18th century and later renovated in the Neo-Renaissance style in the late 19th century by the Šember family.

The castle is famously known as the birthplace of Joseph Radetzky von Radetz, a prominent 19th-century Austrian field marshal. The estate once included a large castle complex with a surrounding park, though parts of the property suffered alterations in the 20th century when it was used by a forestry school.

Today, the castle building remains but is unused, and the park area has been significantly changed. The castle and the adjoining park are protected as cultural monuments.
