NS 991 488. Some slight remains of a broch are situated 650m S of Calla farmhouse on a low rocky knoll (274m OD) at the SE end of Calla Bank. In 1972, only the tops of a few stones could be seen protruding through the long grass that covers the site. The plan, however, shows the features that were visible in 1952, when the site was discovered and planned during a survey of marginal land undertaken by the Commission's officers. At that time the site, which has long been known locally as the 'old quarry', was already in a dilapidated condition, both the broch wall and its enclosing wall being reduced to low grass-grown stony banks. Nevertheless, by clearing back the turf and rubble from a number of facing-stones, it was possible to establish that the broch measured about 11.6m in diameter within a wall varying from 4.9m to 5.8m in thickness. Excavation would be required to establish the position of the entrance and of any intra- mural structures.
The broch stands within an oval enclosure formed by a wall, of which two long stretches of the outer face survive on the NW and SE respectively, but there are no visible indications of the thickness of the wall or of the location of the entrance. The outer facing-stones are set at a distance from the broch wall of as little as 4.0m on the SSE and as much as 12.2m on the N.
Three relics found at the time of the original survey are now in the National Museum of Antiquities of Scotland (NMAS). They are: (i) a roughly circular piece of sandstone, 56mm by 50mm and 14mm thick; (ii) a piece of cannel coal, 106mm by 80mm and 10mm thick, with an incomplete hour-glass perforation near the centre; and (iii) a rough disc of cannel-coal, 25mm by 23mm and 6mm thick, with an hour-glass perforation near the centre.
