Allée couverte de Pir-Han

About

The covered driveway of Pir-Han, also known as the covered driveway of the Feuillay or the covered driveway of the Cavalan Stones, is a covered driveway located in the municipality of Sion-les-Mines in the Loire-Atlantique department.

Description: Jean-Baptiste Ogée gave a very succinct description of it in his Dictionary: "5 huge siliceous blocks arranged circularly, with a dolmen in the center". During his on-site visit, Pitre de Lisle discovers an already ruined monument composed of five quartz stones surrounding a long sandstone stone, with a flat face, arranged on chant. This stone is 2.64 m long by 1.50 m high and 0.75 m thick. Pitre de Lisle identifies him as the southern orthostat of the dolmen. The symmetrical slab facing him was moved and straightened by menhiring with another megalith, the Menhir de la Gree at Midi, in the northwest corner of a calvary built in honor of the Virgin, on the edge of the D1 linking Zion-les-Mines to Lusanger. On the original site, seven blocks (one broken in two parts) are still visible.
