The national cultural monument was designed by architect Adolf Loos and built for the family of František Müller. It houses a study and documentation centre for researchers. The Raumplan space concept was used in the construction. The interior is in the spirit of modern functionalism and classical English style.

The main mission of the centre is to promote modern Prague interwar and post-war architecture, residential culture, applied arts and lifestyle, represented in different ways in the two buildings, in close connection with two important villas - Müller and Rothmayer.

The villa of the architect Otto Rothmayer houses a permanent exhibition The Story of a House and a Family. The exhibition recalls the distinctive style of Otto Rothmayer's architectural work and at the same time seeks to evoke the atmosphere of the living, working and artistic environment that Rothmayer created together with his wife.

Exhibitions and various cultural events are organized in the castle grounds. There is a park adjacent to the castle and weddings are also held there. There is an exposition dedicated to history in the castle, on the 1st floor there is an exposition Crafts in order.
