Stonehenge was built in several phases beginning with an earthwork enclosure around 3000 BCE. Its iconic sarsen and bluestone trilithons were erected centuries later, using sophisticated post-and-lintel engineering. The sarsen stones, each up to 25 tons, were quarried about 25 km away in West Woods, while smaller bluestones came from the Preseli Hills of Wales, over 200 km distant. The stones were shaped with precision joints and aligned to the midsummer sunrise and midwinter sunset.
