The manor is now operated as the Baroniet Rosendal museum. The museum offers valuable information about an important period of Norwegian history.

A guided tour of the manor takes visitors through the different periods of occupation from 1665 up to 1930. The oldest restored rooms are still decorated as they were in the early 19th century. The garden is often referred to as the most magnificent Victorian garden in Norway. Among other things around 2000 roses in bloom can be experienced here from June to November.
