Wilbury Hill bears the traces of a univallate hillfort which was begun in the Late Bronze Age (c700BC). The banks and ditches were improved in the Iron Age, and the site was occupied in Roman times too. You might not be able to see much of what’s left of the two adjoining enclosures, but you’ll certainly get an idea of the fort’s lofty position and views. The fort is right on the prehistoric Icknield Way.
