The Lagatjar Stone Rows are located on the Crozon Peninsula in the Finistère department of Brittany in France near Camaret-sur-Mer. It is believed that 400 menhirs - large and small - should have stood here, which made up the main building with a total length of 600 meters.
And these rows of stones are also of great importance for galactic hitchhikers, as the longest row consists of 42 menhirs with a length of about 200 meters.
In Carnac there are rows of stones (French/Alignments) of menhirs (Celtic/large stone), which consist mainly of granite rock from the Breton coast and numbered around 3000 in the years of construction. The largest menhirs are about 4 meters high and are always at the western end of the corresponding row. To the east, the menhirs become smaller and smaller in their approximately 3 km long rows until they are only half a meter high. Originally, the rows were probably even 8 kilometers long.
