- Summary: Probable Roman fortlet
- Description: NT26SW 33 233 6271
(1) The small camp recorded in 1976 by RCAHMS lies immediately to the SE of the modern road A702 at Glencorse and it probably adjoins the Roman road that ran along the SE side of the Pentland Hills towards Elginhaugh or Inveresk. The ground hereabouts is not cunducive to the free formation of crop-marks and the only photographs available record the side at an advanced and partially lodged state of the crop. The whole of the SW side, 120m long, the E and S angles, and about 40m of the adjacent sides, are all that can be made out. It seems unlikely that the cross-dimension greatly exceeded 100m, and the area was thus not more than 1.2 ha (3 acres).

(2) The E corner, about 60m of the NE and at least 85m of the SE side of a temporary camp have been revealed by air photography on the SE side of the A702 public road 150m ENE of House of Muir steading.
(3) A re-evaluation of the existing aerial photography suggests that the site is a more permanent work than a temporary camp and is therefore more likely to be a possible fortlet.

(4) In December 2007, CFA Archaeology Ltd carried out an archaeological evaluation on the site of a proposed new water treatment works for Edinburgh at Glencorse Mains, near Penicuik, Midlothian. Eighty-eight trenches were excavated, totalling 7280m2 (just over 5% of the proposed development). The evaluation targeted the known location of a cropmark enclosure, interpreted as a possible Roman fortlet. The evaluation confirmed the presence of a rectilinear ditched enclosure, three sides of which were recorded. Sections were excavated across the south-eastern, south-western and north-eastern sides of the possible fortlet, indicating that it measured c.65m from south-west to north-east; the northwestern side of the feature lies outwith the proposed development area but it measures at least 60m south-east to north-west. There were no features identified within the trenches excavated in the interior of the possible fortlet and the entrance was not identified. The ditch ranged in width from 1.1m to 1.8m and up to 0.6m deep.
Other features identified included a series of parallel boundary ditches which relate to plantation boundaries depicted on the First Edition Ordnance Survey 6”map, and a ditched enclosure surrounding a structure also depicted on the First Edition map.
