In this area, flint and limestone fragments occur more frequently.
Their most notable feature is the presence of T-shaped limestone pillars evenly set within thick interior walls composed of unworked stone.
The slabs were transported from bedrock pits located approximately 100 metres (330xc2xa0ft) from the hilltop, with workers using flint points to cut through the limestone bedrock.
