The entrance-passage, though slightly crooked outside the checks and not quite symmetrical inside them, is otherwise of a normal pattern, and the sinuous alignment given to it in Balh'ngaU's plan is quite misleading. Its width is 2 feet 4 inches at the outer end, 1 foot 11 inches at the inner end1 , and about 4 feet behind the checks, the southern one of which is broken. Pig. 1. Ooldoch Broch: plan.
