Only a handful of Iron Age sites still remain in England, with most lost to nature and seemingly destroyed over time. If you walk around the back of an industrial estate in Chelmsford, you’ll come across a rare surviving enclosure which is thought to date back 3000 years to 1000-700BC. Evidence suggests that the site at Springfield Lyons was built on top of an Anglo Saxon settlement and cemetery, but during the Iron Age several roundhouses were built inside of the circular enclosure, similar to the replica one in Hadleigh that we visited.
