Kerzerho, Stone row in Erdeven, France

Kerzerho is a set of Neolithic menhir alignments in Erdeven, Morbihan, made up of roughly 1,100 stones. The main line runs about 2.70 km west to east, bends 120° south of Mané Bras, then resumes its course. Its western end, crossed by the RD 781, holds 165 menhirs in ten more or less parallel files, some over 6 m tall.

The stones were erected during the Neolithic period but later lost their original arrangement. In the 19th century, French authorities restored and repositioned them to their historical places.

The arrangement reflects how Neolithic communities shaped their land and what stone meant to them as a society. Visitors can still see today how carefully each menhir was positioned within the larger plan.

The site is accessible year-round and features a marked trail connecting the various stone formations. The walk takes about two hours through open fields, so visitors should be prepared for weather conditions and wear suitable shoes.

The giants of Kerzerho form a small secondary row of 23 stones about 75 m north of the western end, not at the northern end of the main alignment. Three of them exceed 6 m in height, and one is called the Table du sacrifice. One stone here bears a finely worked shield-like engraving, the only undisputed parietal art known in the region's megalithic rows.
