NO. 4 ENCLOSURE
This is the most westerly of the temple enclosures. Its form resembles that of a keystone with the broad side on the west main wall, along the inside of which it extends for 67 ft. from (666 ft.) to (730 ft.)
It is bounded on the north side by the divisional wall separating it from No. 3 Enclosure, and this side is 47 ft. 6 in. long. This wall extends from the outer face of the west portion of the wall of No. 1 Enclosure for 14 ft., from which it is in a good state of preservation, except for reduction in height, it being now only between 4 ft. and 6 ft., while the rest of the wall is ruined, and is lost in a line of débris which marks where the wall once stood. At the west end of this débris are a few blocks still retaining their position, and these show where the north wall joined the main wall. As on the north side of this wall, where there is now no trace of entrance between Nos. 2 and 3 Enclosures, so is it on its south side, where the face of the wall is even more ruined than on the opposite side.
On the south side this enclosure is bounded by the divisional wall between it and No. 5 Enclosure. This wall is 58 ft. long, and bends southwards in the middle of its length for 5 ft. from a line between the two extremities of the wall. At the east end of the wall it is 6 ft. high for 5 ft. in length, when it is reduced to 2 ft. with débris 3 ft. higher lying along the summit. The west end of the wall is very poorly built, and as this enclosure has also been used by the Makalanga as a cattle kraal, probably finding the wall broken down at its western end, they rebuilt it in order to keep in the cattle. The wall throughout is built on a raised cement foundation only slightly wider than the wall itself.
Though there is at present no trace of any entrance between this and No. 5 Enclosure, there are reasons for believing that traces of one may be discovered near the spot where a large fig tree grows on the line of wall.
The east side is 33 ft. in length, and is formed for 10 ft. from the north side by the west outer face of the wall of No. 1 Enclosure, which is here 11 ft. high; for the following 12 ft. by the opening into the West Passage which runs parallel to the south-west and west sides of No. 1 Enclosure; and for 13 ft. by the outer and west face of the West Passage, the wall of which is 10 ft. high, and is well built, substantial, and in a good state of preservation.
The whole of the interior of this enclosure has been deliberately and rudely filled in with soil, débris, also with stones which have fallen into it, and for almost 2 ft. in depth it is covered with rich vegetable mould. [This latter was removed in 1903.]
