Hillforts are ancient fortified settlements built on elevated ground, often surrounded by earthworks such as ditches and banks. They were primarily constructed during the Iron Age and served as defensive structures for communities. The elevated position provided a strategic advantage, allowing inhabitants to spot potential threats from a distance. These sites often housed a mix of residential, agricultural, and communal buildings, reflecting the social organization of the time. Hillforts were common in regions like Britain and Europe, and their remains can still be seen today, offering insights into early human settlement and defense strategies.
