Gut Altfresenburg: Herrenhaus, Manor house in Bad Oldesloe, Germany

Gut Altfresenburg's manor house was built in 1791 by Christian Frederik Hansen as his first manor in Schleswig-Holstein, a two-storey brick building with a hipped roof rendered in shell limestone. It is L-shaped and set axially to the farmyard, with slightly indicated side risalits of two windows each and a simply framed main portal crowned by a cornice. The vestibule was fully restored between 2019 and 2021.

The building was constructed in 1791 following designs by architect Christian Frederik Hansen, representing Danish classical style. Its origins trace back to a medieval castle structure from the 1300s that was eventually transformed into the modern manor we see today.

The manor provided shelter to religious refugees during the 1500s, playing a role in the region's spiritual history. This connection to early reform movements remains part of the estate's identity today.

The manor serves as a civil wedding venue operated by Bad Oldesloe's registry office, with ceremonies held several times yearly. Visitors should arrange visits in advance, as access is limited to scheduled events and administrative purposes.

The estate's name comes from the von Vresenborch family, documented in the 13th century with Otto and Nicolaus von Vresenborch; Fresenburg later became Altfresenburg. The Mennokate on the southern edge, by the road Altfresenburg, is said to have been the home of Menno Simons, founder of the Mennonites, whom Bartholomäus von Ahlefeldt allowed to live on the estate around 1540.
