Oll Gries is probably a medieval stone setting, which consists of four boulders arranged like a small square around a central stone. It was probably a road marker, but the site is listed in the book “Menhire in Deutschland” by Johannes Groht.
From Upschörter Straße (K50), which connects Wiesedermeer with Reepsholt, a sign leads into a dirt road at kilometre 5.9 to the north, walk from here about 700 m to the site.
