Monuments around Maeshowe

The following monuments will be studied with regard to the reappearance of the sun behind the steep slopes of Ward Hill (Glen of Greor and hill belonging to Red Glen) and the Cuilags (Kame of Hoy): Sun path (all around 3000 BCE).: A more precise view of the above locations can be viewed in the 3D world.

Other candidates (but less important I expect):
