The Spyker Castle and estate lie on the territory of the municipality of Glowe in the district of Vorpommern-Rügen in the German state of Mecklenburg-Vorpommern. Spycker Castle is the oldest profane structure on the Baltic Sea island of Rügen.
Spycker was first recorded in 1318. It belonged at that time to the Stralsund patrician family, the von Külpens. In 1344 a daughter from the House of von Külpen married the Jasmunds. As a result, the Spyker branch of the von Jasmunds was founded which died without issue in 1648.
As a result of the Thirty Years' War, Pomerania, and hence Rügen, fell to Sweden under the Treaty of Westphalia in 1648.
