Karlova Koruna (German: Karlskrone) is a château in the town of Chlumec nad Cidlinou in the Czech Republic.

The High Chancellor of Bohemian Kingdom count František Ferdinand Kinský (1668 – 1741) decided to convert the building into a folly corresponding to the reputation of his noble family.

Some of the best architects and master builders of that times – Jan Blažej Santini-Aichel and František Maxmilián Kaňka – were engaged to create this work of art.

The central high cylindrical body of the building is occupied by a three storied main hall to which 3 wings are connected.

Due to this combination of dynamical design and modest decoration is Karlova Koruna chateau considered to be one of the best Santini-Aichl's structure.

Santini-Aichel was probably influenced by Gian Lorenzo Bernini's studies of using centrally planned building for designing profane architecture.

The Karlova Koruna chateau, situated on the top of small hill, was created as point de vue of the neighbouring park.

Many remarkable species grow there – e.g. European black pine (Pinus nigra) or Turkish hazel (Corylus colurna).

In early 19th century orangery designed by Kinský's master builder Heinrich Koch in Empire style was built.

– visited the place twice (in 1723 and in 1732), king Friedrich II of Prussia (who shortly occupied Chlumec in 1742), the Empress Maria Theresa (in 1743).
