...another gem from Woodhouse!
This sounds fantastic- I've visited the nearby Ardestie souterain, but would never have considered this place as Woodhouse says- it's not mentioned in any of the classic souterrain texts.
'The main tunnel is 12 feet across'- jeez, this sounds like a huge structure. I've come across another circular souterrain structure in Grain souterrain in Orkney;

it's fairly large, but can't remember how big it was! You wouldn't be getting sheep in there though as the steps down into the souterrain are v v steep.
Wodhouse- couple of questions for ya- are any of the structures still roofed? and how on earth did you find out about this place? (or did you go to check out the broch?)
sad-ol-souterrain-lover,
Martin!
