Stonehenge

Prehistoric stone circle; 5,000-year-old mystery on Salisbury Plain

🇬🇧 England Wiltshire 3000 BC

🗼 Why It Matters

Built in phases from 3000–1500 BC — its precise purpose remains unknown

Aligns perfectly with summer solstice sunrise and winter solstice sunset

Some stones came from Wales 240 km away — transported without modern technology

Stones weigh up to 25 tonnes; how they were moved 240 km is still debated
