The listed Hue de Grais manor house in Wolkramshausen is an impressive half-timbered ensemble with a park in private ownership. Step by step, the Werthern family, great-grandsons of the former count's family, are pressing ahead with the renovation of the 18th century property after decades of vacancy.

The restoration work, which was carried out in accordance with the preservation order and about which guests can find out more on the website, was awarded the Federal Heritage and Environment Prize. The former manor house transports visitors back to the Baroque era with its large murals and historic furnishings. The country estate got its unusual name for the region when the daughter of the Wilhelmine von Wilcke family married Achilles François Ursin Hue de Grais, the French envoy to the court of the Landgrave of Hesse-Kassel. Since then, the "Neuwilcke Estate" has been known as "Hue de Grais Castle". The most famous member of the family is probably Robert Count Hue de Grais, who was a Prussian member of parliament and government president in Potsdam.

The ensemble of monuments consists of a three-sided courtyard complex with a two-storey Baroque manor house, to which a three-sided staircase leads from the courtyard side and an attached library as well as an outbuilding on one side and a barn on the other. The library was built as a solid structure of hewn shell limestone with a mansard hipped roof and a façade structured by pilasters. A segmental-arched decorative gable frames the von Wilcke/von Wurmbsche alliance coat of arms. The art-historical significance of the monument lies in the interior decoration from the Baroque period. The representative rooms, laid out in an alignment based on the French model of the Maison de Plaisance, are adorned with decorative paintings or precious damask fabrics.
