Uncle John’s ancestral homeland might just be Scotland. Check out the recently discovered Drum castle toilet.
Toilets were developed around the world, independently, thousands of years ago, but archaeologists keep finding older and older prototypes in Scotland. One of the oldest was found by archaeologists in the 1850s at Skara Brae, an ancient settlement on Mainland, the largest of the Orkney Islands off the coast of Scotland. Several stone huts among the ruins contained drains that extended outside their walls. Historians believe that the huts, which date back to 3,000 BC, were one of the first, if not the first, indoor bathrooms on Earth.
