Piper wall

17th century. Piperska Muren is an ore farm built on Kungsholmen in Stockholm during the 17th century and purchased in 1694 for 9,000 dal copper coins by the courtier Count Carl Piper. In 1702, his wife Christina Piper had a high wall built of rose-layer sandstone, which became popularly known as the Piperska Muren. The property has been owned since 1807 by the Stockholm Lodge of the Coldinuorden. //Wikipedia
