Archaeological view
The mound is about 13m across and 2.6m high. It looks round in profile, but its basal stone rows were laid out to form an octagon; a square forecourt on the south makes it unlike a simple regular octagon. The city’s designation summary and the Agency date it to the mid-7th century, while the city’s detailed account proposes around the second quarter of that century. The passage of its corridor chamber projects unusually into the main room. The Agency records Sue and Haji pottery fragments and one iron nail; the occupant is unknown.
