Unfortunately, not much can be seen anymore of an early medieval hill fort, where a redoubt was built during the Thirty Years' War. However, it is assumed that a Hünenburg/Volksburg existed here in the 8th-9th centuries. More information can be found here: - https://de.wikipedia.org/wiki/H%C3%BCnenburg_(Rheine) - https://de.wikipedia.org/wiki/Kriegerdenkmal_H%C3%BCnenburg - https://www.ebidat.de/cgi-bin/ebidat.pl?id=3327

The large Hünenborg memorial was erected in 1927 and commemorates those who died in World War I. Its style is reminiscent of the Stonehenge stone circle. The battlefields of World War I can be read on the upper ring, both inside and outside. The altar inside the circle features a cross in relief. The years 1914-1918 are engraved on the back of the altar. On the front is a plaque that reads "To our fallen comrades - The Rheine War Veterans Association." The names of the fallen soldiers are listed alphabetically on the pillars. From the Thieberg, you have a wonderful view over Rheine and the Teutoburg Forest. The word "Thie" comes from the "Thing" (Thing) and indicates that a Thing site was located here. The meadow/park on the Thieberg is freely accessible and features both young and old trees. Approaching from the south, one walks along a straight axis toward the monument and is greeted by two low, square stone columns with torches. These columns commemorate the fallen soldiers of the German-Danish War of 1864/66 and the Franco-Prussian War of 1870/71. A little further to the left are two smaller memorial stones: The first memorial stone bears the Bundeswehr Cross and the inscription "In remembrance of the dead." The second, smaller memorial stone has two plaques mounted on it. They commemorate the members of the 15th Army Aviation Regiment (with coat of arms) who died when a helicopter crashed in Kabul in 2002.

To the east of the Great Holy Sea is the Small Holy Sea, which is privately owned but also protected. To the southwest are the sinkhole lake and the Heideweiher pond. The sinkhole lake was formed on April 14, 1913, during the last major sinkhole in the protected area.
