Stonehenge is one of the most monuments in the world. Located about eight miles northwest of Salisbury, Great Britain, Stonehenge is a set of earthworks surrounding a grouping of large, standing stones known as megaliths. Considering Stonehenge is about 4,000-4,500 years old, Archaeologists still aren't sure how the people of that time moved and the stones. Archaeologists are also of what Stonehenge was meant to or how it was to , though many exist. Some believe Stonehenge was used as an ancient , others believe it was built as a permanent stone symbol of the more numerous wooden that were built in the area, and still others believe it was built as an landing site!
