South West Scotland - Dumfries and Galloway

The topmost picture is Cairnholy 1, a very large burial mound aligned to the midwinter sunrise (SE). Another myth about stone age monuments is that the Summer Solstice was the main event in the neolithic religeous calendar. However, anyone with a map and a little astronomical knowledge will soon work out that these aligned sites make much more sense for a Winter Solstice function.

Torhousekie Ring Torhousekie Ring is of a type normally found in Ireland and is Neolithic. 
Note the clear grading of the stones in the ring - the tallest are on the south-east side. The three central stones are aligned NE to SW. Access and parking are made very easy.
Glenquicken

Glenquicken is difficult to get to; there are no signposts, and there are fences and walls to negotiate, but these are nothing compared to the bloodsucking flies - I could feel their jaws biting as this photo was taken! 

A large central stone dominates this Neolithic circle, (for scale, I stand next to it at 194cm) which also has its biggest stones on the south-east side.

Several other circles were nearby, but I was not aware of them until recently!
