Alignements du Gueldro, Stone rows in Plouhinec, France

The Gueldro alignments are the remains of at least eight rows of menhirs at Plouhinec in Morbihan, of which 96 stones survive, some lying on the ground. The rows once ran for several kilometres and held stones 4 to 5 metres tall. In the grass, rough grey stones mottled with lichen stand in a line, one broad rounded stone low in the foreground and taller irregular slabs behind; a pale house with a dark pitched roof stands at the edge.

The stones were erected during the Neolithic period, likely thousands of years ago, serving ritual or navigational purposes for ancient populations. Official recognition came in 1963 when the French government protected the site as a classified historical monument.

The name Gueldro is also recorded as Kerzine, and the rows were once likened to a second Carnac. Two menhirs were broken by quarrymen in 1907, and stones were later moved several metres for road widening. During the Second World War, stones were taken for bunker construction.

The site is easily reached from the main road passing through Plouhinec village. Wear sturdy shoes, as the terrain is uneven and the stones sit directly on the ground surface.

At least eight rows of menhirs, some 4 to 5 metres tall, once ran for several kilometres here, leading to the nickname "a second Carnac". Most destruction happened in the 19th century, and during the Second World War stones were taken for bunkers. Two menhirs were broken by quarrymen in 1907.
