NO. 13 ENCLOSURE
This adjoins No. 12 Enclosure on the north side, the west side of the inner wall of the Parallel Passage forming its eastern boundary for 25 ft. 6 in. This wall is 5 ft. high for 18 ft. from the south end of the enclosure, and 11 ft. 6 in. high for the last 7 ft. of its northern end.
The south side is formed for 12 ft. by the wall separating this enclosure from No. 12, but No. 13 being at a lower level, this wall is 6 ft. high from the present filled-in surface of the enclosure.
The north and north-west side is formed by a wall 32 ft. long, with a rounded entrance from No. 14 Enclosure between the 21-ft. and 23-ft. points of this length, measuring from the east end of this wall. The wall is fairly well built at its eastern end, where it is still 4 ft. high and 3 ft. 6 in. to 4 ft. wide on its present reduced summit. This wall is built upon a red cement foundation. The south-west end of the wall is very dilapidated, but appears to have been originally of good construction. [Owing to piles of soil débris on the south-west side of this enclosure, it is impossible at present to define the exact limits on that side, but the shape of the enclosure is that of a keystone, its widest and rounded end being on the east side.]
