Landsöhr Castle (German: Burg Landsöhr), also called Landseer Castle (Burg Landseer) or Bertaburg, is a lost spur castle on a northern spur, 739.2 m above sea level (NHN), of the Kornberg near Bad Boll in the county of Göppingen in Baden-Württemberg.
The castle was probably built during the Celtic period as a refuge castle. The present burgstall only consists of two hollows between which the castle was probably located.
In the 12th century Berta von Boll, a sister of King Conrad III, is supposed to have had her dower seat here.
