Standing in the Wiltshire countryside of England, Stonehenge is one of the world's most iconic and oldest human-made landmarks. Built over thousands of years, it is the only surviving stone circle of its kind and has become a site of incredible archaeological importance. Although it has revealed much about ancient practices, the structure remains shrouded in mystery - we still can't be sure what it was built for. The most popular theory is that it was a prehistoric temple, as the stones are precisely aligned with the movements of the sun across the sky.
Stonehenge's construction began in 3100 BCE, when a large circular ditch was dug using tools made from antlers. Around this time, the site was used for burials - in fact, it's the largest late Neolithic cemetery in the UK. In 2500 BCE, the massive stones were erected, having been worked into shape and smoothed using sarsen and flint hammerstones. A few hundred years later, the stones were rearranged into their final position. Over the years, many of the stones have toppled or been removed, leaving Stonehenge in its current state.
