SOUTH APPROACH TO NO. 10 ENCLOSURE
This is formed by a passage 10 ft. long, which enters this enclosure at its south-east corner. It is probable that this passage was much longer, and that it once extended to the north-west corner of the Sacred Enclosure, where is an entrance facing the passage.
The west side of the passage is formed by a wall 14 ft. 6 in. long, 4 ft. high, and 3 ft. 6 in. on its present reduced summit, which wall is also the east wall of No. 7 Enclosure.
On the east side is a very well-built wall 10 ft. 6 in. long, 4 ft. 6 in. high, and 3 ft. wide on its present summit, with a finely constructed rounded end tapering upwards and facing south. The rounded end is 7 ft. high, and rises from the floor of No. 9 Enclosure, which is on the east side but on a lower level.
The south end of the passage is 4 ft. wide, but the north end is 6 ft. 6 in. wide, but is narrowed to 2 ft. 6 in. by a rounded buttress 4 ft. 6 in. high, and this and the rounded wall opposite, which forms the other side of the entrance, have upright portcullis-like grooves.
The floor of the passage is paved with flat shallow stones covered for 2 in. in depth with granite cement.
