A mysterious Bronze Age wooden circle known as "Seahenge" on England's east coast was built more than 4,000 years ago in an effort to bring back warmer weather during an extreme cold spell, a new study suggests.
The theory is a new attempt to explain the buried structure — a rough circle about 25 feet (7.5 meters) across, made from 55 split oak trunks surrounding a "horseshoe" of five larger oak posts around a large inverted oak stump — that was controversially dug up and moved into a museum in 1999.
