On the south side of the broch lies Structure J, tucked snugly against the outer wall face of the broch, and partly contained within a revetment wall designed to support the great terrace edge that was dug during the founding of the broch providing the platform on which the broch was constructed.
Structure J appears to be multi-cellular and multi-phased in its design and layout.
A floor level, with paving and a drain has been reached, but it may only be the uppermost of a series of successive floors.
Structure J may well turn out to be very important in informing us as to whether elements of the village were founded at the very same time as the broch was built, or a little after.
For now, we can say that radiocarbon dates show that it was abandoned and infilled at the same time as the broch in the later 2nd or very early 3rd Century AD.
