Dennert Fir Tree

The Dennert Fir Tree (German: Dennert-Tanne, also known as the Dennert’ scher Tannenbaum, Dennert-Tafel or Dennert-Fichte) is a signboard that is used throughout the Harz mountains in Germany to provide information about mining and other points of interest in the area.

It was sponsored by the Power and Water Management Division (Kraft- und Wasserwirtschaft GmbH) of Preussag AG, the operator of the Upper Harz Water Regalem at that time.

Underneath a hammer and pick symbol, the type of site is described together with important information.

The Upper Harz History and Museum Society maintain over 200 signs within an area of 100 km2 (39 sq mi).

Dennert Fir Trees that are set up by municipalities or branches of the Harz Club have the shield of their respective village at the top instead of the hammer and pick.
