Hillforts, rampart by rampart.

The great earthworks of Britain and Ireland: who built them and when, how ramparts, ditches and gateways worked, what life was like inside, and where to see them. Every fact is checked against English Heritage, the National Trust, Historic Environment Scotland, the Atlas of Hillforts and other sources, and where sources disagree we show both.

The short version

Hillforts were mostly built in the Iron Age: the oldest date to around 1000 BC and the most recent to about AD 700. University of Edinburgh: Atlas of Hillforts of Britain and Ireland site launched Hillfort building began across Britain over 2,600 years ago, perhaps marking the rise of larger tribal groups ruled by new elites. English Heritage: History of Maiden Castle

Despite the name, not all hillforts are on hills, and not all were forts in the military sense. University of Edinburgh: Atlas of Hillforts of Britain and Ireland site launched Many may have been regional gathering places for festivals and trade, and some are on low-lying land. University of Edinburgh: Atlas of Hillforts of Britain and Ireland site launched

A hillfort with several ramparts is called “multivallate”, meaning multiple ramparts. English Heritage: History of Old Oswestry Hillfort A “univallate” fort is a hilltop enclosure with a single rampart, a ditch and a low counterscarp bank. National Trust: History of Cissbury Ring

Ramparts were formidable obstacles, but they may also have been built for display, showing off the power of the people inside. English Heritage: History of Old Oswestry Hillfort

Rings of ramparts

Old Oswestry has five sets of ramparts, the outermost being the newest; in places they are over 6 metres high. English Heritage: Description of Old Oswestry Hillfort Entrances began as simple gaps but were rebuilt into long entrance corridors, so people coming in could be watched.

And people lived inside

A community of 300 to 400 people lived at Danebury for more than 400 years. Hampshire County Council: Danebury Iron Age Hill Fort Local Nature Reserve At Uffington, each large round hut probably housed an extended family.
