Orientations of double menhirs
All alignments are accurate to within three metres (5m in a few cases). In most cases they contain four or more points, accurately aligned.

All alignments have been triple-checked. If you find errors or have amendments or something to add, get in touch!

When an alignment passes near a significant site but more than five metres from it, the site is noted in parentheses in the alignment notes on the map, but is not counted as a validating point on the alignment.
Azimuths. In the info popup for each alignment (click on it) and in the alignments list, azimuths are given like this: AZ=84.6°. These show the alignment's orientation, measured in degrees from due north in a clockwise direction. For the opposite azimuth, add 180°. These azimuths apply only to a level horizon.
