Alignements des Landes de Cojoux

The Alignements des Landes de Cojoux, also called the Alignements du Moulin, are three megalithic stone rows at Saint-Just in the French department of Ille-et-Vilaine. The site is classified as a historic monument by decree of 10 July 1978. It was excavated from 1978 to 1981 under Charles-Tanguy Le Roux, with the whole of alignment B and the western part of alignment C investigated.

The site includes three rows named A, B and C, or west, south and north. Two long rows run east-west along the summer solstice, while the third lies at right angles, so the axes cross at the southwest corner. Row A is the smallest, 25 m long, with five blocks of white quartzite. Row B extends about 270 m and is 70 m wide, with 13 menhirs made from red schist, blue schist and white quartz. Row C stretches 120 m and contains 6 massive blocks of white quartz and schist.

Charcoal recovered on the old land surface in row B was dated by carbon-14 to between 4570 BCE and 4370 BCE, and the western part of this row may be the earlier construction. Archaeologists found six hearths, setting pits, packing stones and evidence that one menhir was missing. Near the fifth block of row C, excavations uncovered a small funerary monument with two Bronze Age graves, one built partly against the menhir.

Archaeological material belongs to two distinct periods, the Neolithic and the Copper Age or Bronze Age. Finds include six tranching arrowheads in flint, five further tranching arrowheads, microliths, two polished axes, scattered Neolithic pottery and four bell-shaped beakers. A funerary urn 0,55 m high, decorated with four horseshoe-shaped handles, was buried in row B; its charcoal dated to between 2780 BCE and 2180 BCE.
