Architecture, archaeology and continuing use

A level inner platform about 7.4 metres across is enclosed by a shallow ditch and low external bank, together measuring roughly twelve metres. Small horizontal stones revet part of the bank, and a narrow break on the east-south-east marks the single original entrance.

Its story

The enclosure probably dates to the Neolithic. Partial excavation in 1971 found dark earth and quartz chips. A 2003 investigation supported interpretation as a small henge and recorded possible stake holes, a central setting and an upright stone near the entrance.

Why it is included

Scheduling recognises a well-preserved example of the small henges characteristic of the eastern Highlands and its potential to illuminate ritual construction and land use.

What to notice

  • The single entrance crossing both bank and ditch.
  • A central platform only a few paces wide.
  • Low stonework revetting the outer bank.

Reading the surroundings

Do not scrape, probe or walk repeatedly over low earthworks. Verify lawful access, wear suitable footwear for wet ground and leave all stone and vegetation undisturbed.

Timeline

  1. 3500–2500 BC (probable) A small ceremonial enclosure was formed near the loch.
  2. 1971 Limited excavation exposed dark earth and quartz fragments.
  3. 2003 Geophysics and excavation strengthened the henge interpretation.
  4. 2004 The site entered the national schedule.

What we know — and what remains uncertain

The precise date, activities and central feature remain unresolved, and the 1971 work was not formally published.
