Fortingall

In a field on the north side of River Lyon (Perth and Kinross) are the remains of three stone settings. They were probable stone circles (two four-posters and one reminiscent of a recumbent stone circle).
The northernmost setting comprises three rounded boulders, out of a probable eight, originally arranged in a rectangular setting, with the largest stones at the corners.
In the second setting four boulders are still visible but there were originally eight. In the last one (in the photo) three stones survive, a central massive boulder flanked by two taller uprights, as in recumbent stone circles.
The site was excavated in 1970.
