BUCKINGHAM, ENGLAND—Last week, David Jacques of the University of Buckingham discovered a Stone Age dwelling near the constant-temperature spring at Blick Mead, about a mile away from Stonehenge. The house was constructed from a large tree that had fallen. The pit left by the tree’s roots was lined with stones, and the tree itself was used to make a flint-lined wall. A roof was fashioned from animal skins, and nearby, a stone hearth has also been uncovered. Large stones placed near the wall may have been heated in a fire and used for overnight warmth. “This is a key site for where Britain began. It is the only continuously occupied Mesolithic site in Western Europe and we believe the ‘eco’ home is the sort of place the first Brits lived in,” Jacques said in a press release. Plans to build a tunnel to accommodate Stonehenge traffic could destroy the site. To read more, go to "Under Stonehenge."
