The pride of the village of Chtelnica is the mansion from the late 16th century, which was owned by a significant noble Erdődy family. The renaissance appearance of the mansion was changed to baroque in 1769 and it has been preserved to this day.

Chtelnica manor is registered in the register of national cultural monuments. The whole building consists of a centrally located main building of the mansion, which is surrounded by four pavilions. The premises of the manor house became the seat of the regional museum, whose activities focused on documenting and presenting the history of the former town of Chtelnica and its surroundings.

In the eastern pavilion is the Chapel of the Crucifixion, which was built in 1769 by Count Erdődy. The chapel is open to visitors to the museum. In the northern pavilion, the Small Carpathian Gallery was created, which offers visitors the opportunity to get acquainted with the artistic activities of the work of regional artists.

Behind the mansion, there is a large park with a pond, which also serves as a space suitable for organizing various social events and for the home is a pleasant place for walks and relaxation.
