Cairnpapple Hill

This is the neolithic burial mound at the top of Cairnpapple Hill, near Bathgate. Although it dates from around 3500BC, the upper dome and steps I think were constructed in recent times to allow visitors to go inside it and view the reconstructed graves. More about it here.
It came to mind today when I checked what the Mono Monday theme was, which is stairs or steps.
