Origin and history

The covered street of Luffang Tal-er-Roch, located in Crach, Morbihan, is a neolithic funerary monument. Discovered under a circular tumulus of 46 m in diameter today disappeared, it was partially destroyed in the 19th century by carriers who cut its slabs and two neighbouring menhirs (including Er soudard-cam, 4 m high) to build a lighthouse in Belle-Île. The site, searched in 1868 by local vicars and then in 1898 by Zacharie Le Rouzic, revealed pottery, flint tools and bronze trimmings, showing complex funeral practices.

The 22-m long, wide, broad, winged at 45° after 7 m, oriented north-west. Among its 19 orthostats preserved (1 to 1.90 m high), three have engravings, including an exceptional representation of octopus (0.95 m high) on the third left support. The soil, partially paved, was inclined and disturbed by previous looting. The excavations of Le Rouzic confirmed the sepulchral vocation of the site, with coals, flints and vases decorated among the remains.

Ranked a historic monument on October 10, 1938, covered lane illustrates Breton megalithic architecture and the risks of heritage destruction in the 19th and 20th centuries. The missing menhirs, associated with local legends ("the lame soldier" and "his wife"), underline the symbolic importance of the site before its partial dismantling. The objects discovered (polished axes, flint arrows, if bracelets) are today references for the study of the Armenian Neolithic.
