Grafensundern, Summit in Iburger Wald, Germany

Grafensundern is a mountain rising to about 315 meters within the Teutoburger Wald region of Lower Saxony and features sandstone rock formations. The terrain is marked by marked hiking paths like Hermann-Wesseler-Weg and Grafensundernweg that cross through the area.

The oldest boundary stone found near Bad Iburg dates from 1732; most such markers were cut from sandstone and recorded whether land belonged to the prince-bishops, a monastery or private owners. The Grafensundern itself belonged to the prince-bishops of Iburg, and earthen boundary walls reinforced the stone markers. Its territory ended to the west at the road Achter de Welt.

A few metres north of Landesstraße 96, where the Karussellstraße begins its climb over the southern slope, stands a Heiligenhäuschen: a half-open brick shrine about 2.5 metres tall. On a pedestal inside is a carved wooden figure of Mary. Such wayside shrines marked paths and field boundaries in this part of the Iburger Wald.

The summit is reached via the Kammweg, which branches off the Karussellstraße at Karlsplatz; the Karussellstraße itself leaves Landesstraße 96 south-southwest of the hill. The Hermann-Wesseler-Weg and Grafensundernweg also cross the slopes. The paths are unsurfaced and uneven in places.

A communication tower built in 1965 stands near the summit and rises 60 meters high. The structure supports digital radio and amateur radio services and is visible from many points on the mountain.
