Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Sarsen stones are sandstone blocks found in quantity on Salisbury Plain, the Marlborough Downs, in Kent, and in smaller quantities in Berkshire, Oxfordshire, Dorset and Hampshire. They are the post-glacial remains of a cap of tertiary sandstone which once covered much of southern England, a dense, hard rock created from sand bound by a silica cement, making it a kind of silicified sandstone. The builders of Stonehenge used these stones for the heelstone and sarsen circle uprights. Avebury and many other megalithic monuments in southern England are also built with sarsen stones. Fire or explosives were sometimes employed to break the stone into pieces of a suitable size for use in construction. Sarsen is not an ideal building material, however. William Stukeley wrote that sarsen is "always moist and dewy in winter which proves damp and unwholesome, and rots the furniture".
