Britain is brimming with ancient monuments. Medieval castles, Roman baths, Megalithic villages. The landscape is littered with them. And the most famous of all is Stonehenge.
It's not the biggest henge in Britain, but the only surviving lintelled stone circle
Stonehenge was expanded and updated by three different populations spanning 1,000 years.
Phase 1: 3000 BC
Work at Stonehenge started around 3000 BCE. That makes it older than the Egyptian pyramids.
Neolithic people used picks made from deer antlers and mandibles to create a ditch, a bank and 50+ large holes. The resulting earthwork may have been a burial ground for the elite.
Phase 2: 2500 BC -- wooden posts
Phase 3 - 2000 BC - bluestones and the henges
----------
These were definitely not built by giants or fallen angels, but by Neolithic men.
