Allée couverte de la Hautière

About

The covered driveway of the Hautière, also known as the Tombeau, is located in Trégon in the French department of Côtes-d'Armor.

Description: The covered gangway is 16 m long. It is south-southeast/north-northwest. It is bounded by fourteen orthostats on the east side and eleven on the west side. The set is covered by six cover tables. The largest measure is 3.05 m long, the others are smaller (about 2.60 m long). The underfloor height is 0.90 m for an inner width of 1.05 m. Most of the blocks are made of quartz sandstone, known as "Armo-American sandstone", the others are in dolerite for some orthostats only or in gneiss-migmatitic. This latter lithology is very minority and particularly visible at one of the cover tables.
