In a quiet patch of green above the River Thames, not far from the bustle of London, lies a hilltop that quietly commands the world’s time. This is the Royal Observatory, Greenwich—home of the Prime Meridian, keeper of Greenwich Mean Time (GMT), and arguably the most important line on Earth that you’ll never actually see in daily life... but absolutely can *stand on* here.

If Stonehenge is the popular rockstar of Britain’s ancient monuments, then Avebury is the deep-cut album that true fans obsess over. Quieter, stranger, and — believe it or not — *bigger*, the Avebury Stone Circle is a prehistoric mystery that sprawls across the Wiltshire countryside like a forgotten whisper from an ancient world.
