Knutstorp estate was first mentioned in the mid-1300s. It was owned by the powerful Danish family Brahe until 1633. In 1771 Knutstorp was sold to Fredrik Wachtmeister and it has been since owned by his family.
The main building dates from the mid-1500s. It was built by Otte Brahe and is the birthplace of the famous astronomer Tycho Brahe (born 14 December 1546). After the occupation of Sweden King Carl XI ordered to strenghten Knutstorp as a stronghold. Danish army conquered it in the same year and the main building was damaged by fire. It was restored in 1728 and again in 1840s. Two wings were destroyed by fire in 1956.

Its name Červená Lhota meaning 'red lhota' can be explained by the colour of the château"s bright-red roof tiles. There is also a park, where the Chapel of the Holy Trinity is located.
The existence of an original fortress on the site of today"s château is assumed from sometime around the middle of the 14th century. It was built on a rocky granite outcrop, which, after the damming of a stream and the filling up of a fishpond, became an island. The first written source is an entry into the land records from 1465, mentioning the division of the property of deceased Ctibor of Zásmuk between his two sons Petr and Václav.
