Here's some really, really old rocks

Continuing on our wait-until-things-magically-fall-into-place tour, we braved the biting cold to check out Stonehenge, a 4,500 year old group of rocks arranged in a circle, which certainly doesn't sound all that incredible until you see the sheer size of them. It was pretty awe-inspiring to imagine the phenomenal feats of strength, engineering, and pure tenacity in getting such massive stones upright. For scale, some of the trilithons (three stone structures with the 'roof') are over 7.3m (24ft) high and weigh over 35 tonnes - that's 10 times the size of our motorhome!

The outermost setting was a circle of 30 upright sarsens (large sandstone), capped by horizontal lintel stones. Only 17 are still upright today. These were carefully shaped to fit into each other, Lego-style, to ensure they withstood the test of time.

One of the most intriguing things we learned was that the inner bluestones, each weighing up to 3 tonnes, were brought from a standing circle in Wales - over 240km away! Now that is determination.

Fun fact! Stonehenge has nothing to do with Druids - that was all a 'guesstimate' from a 17th century writer. The Druids didn't even emerge until a thousand years after Stonehenge! What is more likely is that Stonehenge was the ancient equivalent of a cathedral, as the bluestones were believed to have healing properties and there were human remains found in Stonehenge. So Stonehenge would have been a place to come for healing, burying important people, and tracking the winter solstice.
