Wolverhampton was at the edge of the ice sheet in the most recent ice age. All across the city there are scatterings of these large boulders of rock originating as far north as the lake district or Scotland. One such set of boulders have been gathered together on the approach to Bushbury church. There are about twenty of them in the pile, set in cement.
Another is in the garden of Northycote Farm. Perhaps it was used as a mounting stone in former times.
