Grooves (archaeology)

Sw-En translation: sharpening grooves) carved into rock in many places in Europe, and some of them appear on the Baltic Sea island of Gotland.

In Gantofta located 14 km (8.7 mi) south of Helsingborg a face of sandstone rock is engraved with thousands of grooves.

People who built dolmens, erected menhirs and made grooves supported an archaeological culture known as Seine-Oise-Marne.

After some time, newspapers and scholarly publications began to dispute this, since the shape of the grooves makes them unfit for sharpening swords.

Likewise with the level above current sea surface of the lowest grooved outcrops on the island, that shows them to be no older than AD 1000 judging from post-glacial shoreline displacement.
