Gutshaus Dolgen, Manor house in Dolgen am See, Germany.

Gutshaus Dolgen is a neo-Renaissance manor house built on parts of former castle foundations by the von Drieberg family in the early 16th century. Leopold von Plessen rebuilt it in the early 19th century with a mansard hipped roof and a two-storey central risalit, modelled on Orellen Manor in Livonia. The estate also retains a largely original steward's house and remnants of the von Plessen family chapel and burial site.

Dolgen was first documented in 1285, when Nikolaus II of Werle granted the village to the Rostock citizen Nikolaus. The von Drieberg family built a manor house on former castle foundations at the start of the 16th century. From 1782 the estate belonged to Leopold von Plessen, who around 1800 had the house rebuilt as a Neorenaissance mansion with a mansard roof, modelled on Orellen in Livonia. The estate was expropriated in 1945 and became an LPG in 1950.

The name Dolgen comes from the lake beside which the estate lies. The village was first documented in 1285, when Nikolaus II of Werle granted it to the Rostock citizen Nikolaus; it soon passed to the Monastery of the Holy Cross. From 1782 to 1945 the estate belonged to the von Plessen family, whose summer stays under Leopold von Plessen drew statesmen and guests from abroad.

The manor stands in Dolgen am See in the Rostock district, at the end of a village street; the cobblestone avenue that once led to it was removed in the 20th century. The house is now used for residential purposes, so it can be viewed from the public path but not entered. Remains of the von Plessen family chapel and burial site lie on the grounds.

Beneath the manor lies a tunnel from the medieval castle that once stood here; it was still open until 1945, and whether it survived the post-war years is not recorded. The estate's chapel and burial site of the von Plessen family was used as a storage shed from the 1950s, after the dead had been moved to an anonymous mass grave in the Hohen Sprenz churchyard.
