type (centre) and a heel-shaped cairn (right)The heel-shaped cairn, with its usually cruciform chamber, is a type of
Isbister Cairn
is the only site that is similar in shape.
The chambers usually lie in a round cairn made of broken rocks, which either contemporaneously or later were surrounded by the eponymous platform, up to 20 metres wide at the front and from 1.0 to 1.5 metres high, and were partly enclosed by large kerbstones. A gentle concave exedra is characteristic of the front face.
The often cruciform chambers, accessed via a short passage, have a large recess at the head and two smaller recesses to the side. They were covered with
corbelled vaults
, of which however usually only remnants survive. The best-known sites of this type in Shetland are:
Gillaburn, Hill of Caldback, Hill of Dale, Mangaster, Muckle Heog,
Camster Round and Skelpick Long). At the monument of Vementry the round cairn, with the typical chamber of heel-shaped cairns, was built over in the heel-shaped form and given a roughly 10.6-metre-wide exedra
.
