What type of rock is Stonehenge made of? Quick Answer. Although at least 20 types of rocks have been identified at the site, Stonehenge is made from two primary types of stone: sarsen sandstone and bluestone, with the stones forming the external wall of the circle in Stonehenge being made from the former.
Bluestone is a cultural or commercial name for a number of dimension or building stone varieties, including: 1  basalt in Victoria, Australia, and in New Zealand; 2  the dolerite of Stonehenge in Britain.3  a feldspathic sandstone in the U.S. and Canada;he bluestones at Stonehenge were placed there during the third phase of construction at Stonehenge around 2300 BC. It is assumed that there were about 80 of them originally, but this has never been proven since only 43 remain. The stones are estimated to weigh between 2 and 4 tons each.
