Glenarigolach is by far the most extensive settlement N & E of the Gruinard River. It comprises of a complex field system with many enclosures and several buildings.

In an attempt to make sense of this sprawling site (covering about 3 square km), I have taken the liberty of identifying and labelling 9 separate, but related sectors (3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h & 3i).

The heart of the settlement 3f, is surrounded by several satellite enclosures.

The remains of over 20 buildings and other domestic structures make up the heart of Glenarigolach (3f).

A corn-drying kiln and rig & furrow cultivation indicate a thriving community at some point in recent history.
