STONEHENGE Stonehenge is a collection of large stones that were erected in several stages over 5,000 years ago in Wiltshire England Historians are still not sure why Stonehenge was built but some experts believe Stonehenge could have been used for religious ceremonies as a burial ground or for rituals to mark the changing of the seasons Stonehenge is made from two types of stones The smaller stones known as bluestones are a variety of stones not found in the area around Stonehenge The larger stones made from local sandstone are called sarsens The largest of the sarsen stones are 30 feet 9 m tall and weigh 25 tons 22 6 metric tons It has been determined that the builders of Stonehenge transported the bluestones over 236 miles 380 km from Wales The builders only had tools made from wood stone and rope so no one is entirely sure how they managed to transport the stones and build such a huge structure Stonehenge is made of two circles an inner circle built from bluestones and an outer circle built from sarsens 6
