Parts of my local are 600 years old, and there's a Roman road about 5 minutes walk away from my house. I'm always amazed when I look at an Ordnance Survey map and see the amount of tumulus (burial mound) and other ancient structures. We are surrounded by history but mostly unaware of it. I sometimes wonder about what's out there waiting to be discovered. Perhaps one day we'll have archaeological drones roaming around looking for undiscovered treasures.
