Menhir von Mittelbrunn, Menhir in Mittelbrunn, Germany

The Menhir von Mittelbrunn, also called Langenstein or Der Lange Stein, is a pillar-shaped red sandstone standing stone 176 cm tall, 87 cm wide and 45 cm deep, tapering to a rounded tip. Its northwest face bears a cross cut as a boundary mark; other faces carry initials and the year 1852. Otto Gödel believed a heavily weathered human relief could be seen on it.

This stone was already documented in the 16th century as a boundary marker separating two neighboring communities. Its location was maintained as a recognized survey point across subsequent centuries.

The engraved cross on the northwest face marks the stone's former role in territorial division, while carved initials and the date 1852 show how later people left their own marks on the surface.

The stone stands in a field north of Mittelbrunn village and is accessible on foot. Access is via farm roads and paths that remain walkable throughout the year, especially when agricultural work is not in progress.

Otto Gödel claimed to see a heavily weathered human relief on the stone, a reading that other observers have not confirmed. The northwest face instead carries a cross cut as a boundary mark, while other sides show several initials and the year 1852.
