Gut Projensdorf, Manor house in Altenholz, Germany.

Gut Projensdorf is a manor house in Altenholz near Kiel-Holtenau with a rendered white facade, hipped roof, and baroque dormers. The building displays the broad proportions and classic features typical of country estates in northern Germany.

The estate was first documented in 1378 as 'villam Prodenstorpe' and passed through several noble families including von Ahlefeldt, von Rantzau, and von Baudissin. These connections to prominent northern German families shaped its development across the centuries.

The property contains artifacts from Neolithic and Bronze Age times, with burial mounds visible on the Achtstückenberg that show how early people settled this land. These traces reveal the deep roots of human habitation in the area.

The manor is used today as a venue for civil ceremonies and cultural gatherings, with modern facilities including a boarding stable on the grounds. Check ahead before visiting, as the property is often booked for private events.

The manor house dates from 1780 and parts of its original structure survive. A major fire broke out in 2008, but the damage was repaired quickly. The building is a listed monument and opened to the public on Tag des offenen Denkmals in 2010, organised by KulturGut Projensdorf with the municipality of Altenholz and the Canal-Verein.
