Archaeologists working on Salisbury Plain near Stonehenge found evidence of a gigantic circular structure dating back some 4,500 years. The structure once consisted of 20 carefully positioned pits, the largest of which measured more than 16.5 feet deep (5 meters) and 32 to 66 feet wide (10 to 20 meters). Forming a circle, the pits were, on average, around 2,835 feet (864 meters) from the center point, and it’s now considered the biggest prehistoric structure ever found in Britain. Its purpose is unknown, but it could’ve been used to designate a sacred space.
