The great and ancient stone circle of Stonehenge is one of the wonders of the world. What visitors see today is the substantial remnants of the last in a sequence of monuments erected between c.3000 and 1600BC. Each a circular structure aligned along the rising of the sun at the midsummer solstice. Now a World Heritage Site, Stonehenge and all its surroundings remain powerful witnesses to the once great civilisation of the Stone and Bronze Ages.
