Gut Rastorf, Cultural heritage ensemble in Rastorf, Germany.

Gut Rastorf is an 18th-century estate complex in Schleswig-Holstein featuring symmetrically arranged baroque and early classicist buildings set around a central courtyard. The main manor house, smaller cavalier house, and farm structures form a cohesive architectural group within a landscaped setting.

Gut Rastorf traces back to a knight's seat with a water castle and has belonged to the Rantzau family since the 14th century. In the 16th century it became an estate with a manor house; the estate buildings burned in 1720 and were rebuilt between 1723 and 1729 as a closed courtyard complex to plans by Rudolph Matthias Dallin in late Baroque brick, commissioned by Christian zu Rantzau. The manor house was demolished in 1802 and replaced by an early Classicist building erected 1803–1806 under the Danish architect Christian Frederik Hansen. Until Prussia took over in 1867 the estate also held patrimonial jurisdiction.

The estate has belonged to the Rantzau family since the 14th century, and their influence is visible in the family coat of arms carved in sandstone above the central window of the manor house, dated 1724. The layout of the courtyard, with the Kuhhaus and Scheune flanking the axis to the manor, shows the working hierarchy of an aristocratic estate. The gatehouse, 130 meters long, served as both entrance and representation.

The grounds can be explored using marked pathways that connect the main buildings and surrounding landscape. A leisurely walk through the park allows time to observe architectural details and understand how the different spaces relate to one another.

A memorial stone carved from Norwegian marble by Danish sculptor Johannes Wiedewelt stands in the park, honoring a member of the Rantzau family. This work links the estate's story to the artistic traditions of northern Europe.
