Zámek Nemilkov, a Renaissance and Baroque residence, built on remains of a Middle Age Gothic fortress, is a cultural heritage estate on the list of “endangered sights”.

The original Gothic fortress was first mentioned in writing around the end of the 14th century. We still don't know exactly where the fortress stood nor how it may have looked. Only underground passages and cellars remain, and these have yet to have been historically examined. The Gothic fortress was rebuilt as a Renaissance chateau in the 16th century. The courtyard and farm buildings were also built at this time. The chateau was enlarged by the west wing and a baroque front façade by the end of the 18th century. The last important construction took place during the 19th century in the Classicism style (façade and interiors). During the Communist era, the property was used by the state farmers' association and badly damaged. After the Velvet Revolution the premises were privately owned, but never reopened to the public. The Kaplan-Hager family bought the property in September 2016.

There are many secluded places at the chateau where architectural styles meet: secret entrances, mysterious staircases, double ceilings, and enigmatic corners in the labyrinthine cellar, which are yet to be discovered.
