|The chevaux de frise of Bryn y Gaer|
Hill forts are among the most distinctive monuments from the Bronze and Iron Ages in Britain and Europe. Theories regarding them range from fortifications to cattle pens, from grandiose statements of wealth to ritual and religion, but have you ever stopped to consider the amount of work that went into making one?
Nowhere is this question more relevant than at the hillfort of Bryn y Gaer, where as well as the work of making banks, ditches and walls, the inhabitants collected thousands of sharp pointed stones and half-buried them in the sward in front of their defences. Their aim? To keep the fearsome Celtic war chariots at bay.
