The Burg Jesberg, a
castle built by the noble family of Linsingen in 1241, was later sold to the
Archbishopric of Mainz, and along with
Naumburg and
Fritzlar was one of the Archbishops' main bases in the struggle against the
Landgraves of Hesse. In 1723, the
Prinzessingarten — Princess's Garden — near Jesberg was built in what is now the Jesberg State Forest. It can still be seen, along with its centrepiece, the
Prinzessingarten-Eiche, a big
oaktree, although nowadays, little of the actual garden is still preserved. The small
Baroque stately home was built by Maximilian von Hessen, Landgrave Karl von Hessen-Kassel's son — whose four daughters also inspired the Princess's Garden — on the lands near the Treisbach (brook) in the early 18th century. On 9 June 1922, the historian
Hugo Brunner died in Jesberg. ==Politics==
