The hillfort is enclosed by massive earthen ramparts with an entrance at the north end, and a suggestion of one at the south. The first phase of construction took place around 1100-800BC. The second phase belongs to the Early Iron Age (700 - 350BC).

A metre-thick layer of domestic waste demonstrates that it was intensively occupied following the construction of the ramparts. The interior had short grass, either as a result of grazing or human wear and tear.

Later, in the Middle Iron Age, much rarer finds suggest that people did not continue to live there in great numbers.
