The listed building including an abbey, a church, economic buildings and manor house were thoroughly restored over recent decades. The decision was made to maintain the architectural examples from all eras and preserve as an ensemble. Thus, the monastery Haydau is seen as a successful symbiosis of past and future today.

Dating from the 13th century, the complex of the monastery and church hall, still give the impression of a single monastery. Since the monastery was rebuilt into a hunting lodge in the early 17th century, it also contributes significant features of the late Renaissance. The ceiling in the Engelsaal, the applied terraced park, the manor and the Orangery serve as successful examples of Court design and culture.

Now the newly built Hotel Kloster Haydau, a modern construction, completes the historic site. The elongated, simple building is an interesting counterpoint to its medieval surroundings - and integrates extremely harmonious.
