These are on the bank of a slope leading up to housing development behind the old railway track. A local woman out for a walk told me that before there have always been there - before the houses there was a field and the stones were just there. So it seems that parts of old Swindon may have once been near a sarsen drift valley - perhaps where the motorway now runs. These stones would have no doubt been cleared from the route of the railway that used to run from Wootton Bassett to Marlborough via Old Town.
