I guess I might say King John signing the Magna Carta at Runnymede, because it was the foundation for the rule of law in the West. But it was just a bunch of smelly dudes in a marsh. A lot of historical events are important, but not that spectacular to see.
For sure, some events would not be as spectacular to watch. They're still fascinating to think about though.
Standing at Runnymede imagining how it might have happened, and then considering the legacy and impact it had in bringing me back to the spot hundreds of years later.
Hard to say for sure but some things might actually be more fun just to ponder over.
