Scientists in England have found a second structure near the site of Stonehenge. This second structure is comprised of a circle of stone buried deep underground. While some experts argue for the possibility that this could be a “Timberhenge”, or Stonehenge made out of wood  (the wood would have rotted away millennia ago, leaving only the stone bases), most agree that it is actually the site of a barrow, or ancient tomb.

The expedition, led by Birmingham University, uses radar and other  types of scanners to search underground for artifacts around Stonehenge, without actually having to disturb the site. Other wooden structures have been found before in the area, but this is the first significant find in 50 years.
