Sarsen Stone

Sarsen Stone
A type of hard silicified sandstone found scattered naturally across chalk areas of southern England.
Sarsen, a hard rock created from sand bound by silica cement, formed as a crust over chalk geologies. Often fossil root holes can be seen in the stone, from millions of years ago when the stone was still forming. Over time the stone was broken up into large pieces and scattered by geological processes.
