Can you believe that the pyramids of Egypt were built thousands of years ago or that Stonehenge in England still stands today? How do we explain the Nazca Lines in Peru, or crop circles in the UK? Is it true that Mt Everest is getting taller each year? And how did America's deep Grand Canyon develop? Why is it that Hiroshimas' Itsukushima Shrine is in the sea but never gets submerged? We're looking forward to hearing about places that intrigue you, whether they were created by nature, or by human hands. Perhaps there's somewhere interesting in your own country you can teach us about!
