Plaue is on the right bank of the Havel, opposite a flatland that hosts the Brandenburg-Briest Solarpark.
A Slavic burial ground dated to the period between the 10th to 12th centuries was discovered in the course of construction work on the Plauerhof street in the summer of 2001.
Most of the dead were buried in a stretched supine position with side arms and an approximate west–east orientation.
The grave pits were in many cases provided with wooden fittings with clear protrusions from the side and cross boards.
The castle and the town were fiercely contested in the 13th and 14th centuries between the Margraviate of Brandenburg and the Archbishopric of Magdeburg.
The town and castle were owned by various noble families, vassals of the Archbishop of Magdeburg or the Margrave of Brandenburg.
