'''Stonehenge''' is a megalithic monument located in southern [[England]]. The word comes from the Anglo-Saxon ''stone'', meaning 'stone', and ''henge'', meaning 'hinge', because the distinctive upright pylons with their crosspieces were thought to resemble a door or gate. The tallest of these, known as the 'sarsen', is nearly 100 feet high.

The first evidence of construction secular scientists date to around 8000 BC, making Stonehenge the oldest known construction in the world, but it was added to over many thousands of years thereafter, with most of the present structure dating to 3000 BC.

Stonehenge is aligned to the sunrise at the summer [[solstice]], or longest day of the year, around June 21. On that day the sun shines through the sarsen stone and hits something called the heel stone which lights up like a mirror, as it is made of polished quartz.
