Schloss Semlow, Architectural heritage monument in Semlow, Germany.

Schloss Semlow is a manor house in a village in Mecklenburg-Vorpommern with classical symmetrical facades and carefully crafted details. The grounds include landscaped areas surrounding the main building that extend the sense of the estate.

Friedrich Wilhelm Buttel, court architect at Strelitz, built the manor around 1825 for Carl von Behr-Negendank; around 1850 Ulrich von Behr-Negendank added an orangery and a two-storey wing. The family lived here until 1945, when the house was looted and partly destroyed. In 1947 it passed to the municipality and served as school, kindergarten, canteen and library until 1989.

The estate gave its name to a family line: Heinrich von Behr-Negendank (1763–1794) founded the Semlow branch of the von Behr, and the property became a family fideicommissum. In 1939 the Semlow lordship, with the estates Plennin, Palmzin, Karlshof, Koitenhagen, Stormsdorf and Wohsen, covered about 3,800 hectares. The hunting cellar later housed the local youth club of the GDR era.

The castle is located in a village reachable by car or public transport. Before visiting, check which areas are open to the public and whether guided tours are available.

The park once held an entrance flanked by bears and carved with the family coat of arms, a tea house shaped like an ancient temple, and a grotto; all were destroyed after 1945. The east wing's orangery, once crowned by a square tower, still awaits restoration.
