Originally a Gothic castle, founded in the mid-13th century, it was rebuilt in the 16th and 17th centuries during the tenure of the Smiřický family into a Mannerist castle. Its present architectural form was gained during renovations and interior modifications in the 17th and 18th centuries, when it was held by the Italian noble family of Piccolomini. The Early Baroque Spanish Hall spreads over two floors, and there are unique collections of tapestries as well as Baroque flower still lifes. Besides the Smiřickýs of Smiřic and the Piccolominis, other important owners of Náchod included the Duke of Courland and Sagan and the German princely Schaumburg-Lippe family.
