The name does not refer to the Orange River, but to a building style of Blockhouses from the Anglo Boer War. The cache is at the Blockhouse,
Orange River Octagonal Pattern
This type of blockhouse is represented by at least two well-preserved examples, situated, respectively, to the southeast of the road and rail bridges over the Orange River at Norvals Pont [NC] and to the east of the railway line at Riversford [FS], 40 km south of Bloemfontein. The latter is the better to view as the former has been converted into a dwelling, is situated on private property and is largely obscured by creepers. The author has established that a third example of this pattern was positioned to the north-west of the Norvals Pont bridges, this and one other being known from photographs held by MuseuMAfricA in Newtown, Johannesburg. There is now a third blockhouse of this type - it is at the Museum of the Anglo Boer War in Bloemfontein. It was built during 2025 at the Museum.
Three-storeyed, this pattern is in plan a square with the corners cut off, covered with a shallow-pitched corrugated roof which rises to a central ventilation turret.(18) The ground floor has three loopholes in each main wall and one in each splayed corner. The first floor has the entrance door and three shuttered windows respectively at one end of each main wall, with three loopholes in each of the main walls and one at each corner. The top floor has a shuttered window in the middle of each main wall, which opens onto a rectangular machicouli gallery, with two loopholes on either side of each window and, again, one in each corner. The entrance had, unusually, a steel landing outside; with the ladder running against the wall to ground level, (blockhouses generally had a ladder at right angles to the wall). In both surviving examples, the door faced the railway and both still feature a steel gantry hoist fixed to the outside wall by the doorway, presumably to assist with the lifting of supplies into the blockhouse. Internally, the Riversford blockhouse has wall offsets to carry the upper floors, and the floors on both levels were unusual in that railway lines were used extensively in the timber floor construction, partly to support the cantilevered galleries on the top floor, although these are also present at the first floor level. From an architectural perspective, this is probably the most satisfying of the blockhouse designs.
