Some larger circles, such, for instance, as the Bosawen-ûn circle, eighty feet in diameter ([fig. 80]), the Aber circle ([fig. 81]), and others, it is supposed, may have been formed around a group of interments, instead of single interments, as in many of the others. In some instances a single stone was placed to mark the place of interment. Three such exist in the barrow at Berriew ([fig. 82]). A large circle ([fig. 83]), twenty-seven yards, in diameter, on Penmaenmaur, was constructed of several uprights, connected by smaller masonry. Here the interments were apparently made beside the pillars. Against the inner side of the tallest pillar A, on the eastern part, were the remains of a small stone cist; while against the pillar B, facing it on the opposite side, was heaped up a small cairn. The whole is surrounded by a ditch, within which, at C, is another small cairn.

Arbor-Low, in the High Peak of Derbyshire, to which allusion has been made, is represented in [fig. 84]. No sepulchral remains have been discovered within the circle, but barrows of great extent, which have yielded important remains on being excavated, are closely connected with it. It is, however, probable, that interments have existed, and been removed in past ages.
