Nasavrky Castle, Renaissance château in Nasavrky, Czech Republic.

Nasavrky Castle is a Renaissance structure standing on the site of a former Gothic fortress. The building features an entrance hall with ornate portals and displays the architectural proportions typical of its era.

A Gothic fortress mentioned in 1545 stood here before a Renaissance castle was built around 1600 for Václav Záruba of Hustířany. Confiscated from his son Ctibor, it was bought in 1623 by colonel František de Courier and passed by inheritance and marriage to Jan Adam of Auersperg (1721–1795), who moved the estate administration here after 1757. The Auerspergs added a smaller wing and used the castle as a summer residence; in 1840 the second floor was lowered.

The interior houses an exhibition about Celtic life that connects visitors with the ancient history of the Iron Mountains region. The collection shows objects and discoveries from this early period of the area.

The castle stands at the northern end of Nasavrky's main square, about 13 km south of Chrudim, on the edge of a terrain terrace with a garden on the sloping east and north sides. The ground floor holds an information centre and the first floor the permanent exhibition "In the Footsteps of the Celts"; there are no guided tours, as the halls serve exhibitions, concerts and weddings.

The castle cellars are inaccessible and filled in; legend says a tunnel runs from them to the ruins of Strádov Castle in the Slavice game park near Slatiňany. The park was also founded by Jan Adam of Auersperg, as was the chestnut orchard Kaštanka about 100 m north of the castle in 1776.
