Exmoor also has a henge, near Parracombe, although it has been damaged by ploughing. Alongside this, the moor bears a profusion of other Bronze Age monuments, including between 300 and 400 round barrows, standing stones, linear stone rows, and stone settings. The creation of these different monument types might also explain why so few stone circles were apparently created here. Most of the surviving prehistoric stone monuments on Exmoor are located on those areas of moorland outside the limits of medieval and post-medieval agriculture. For this reason it is likely that the surviving sites are not a reliable indicator of the original extent of these sites.
