and his name was llywelyn fawr, which means "llywelyn the great" in welsh. and he really was great, he was an amazing man. he at the time, wales wasn't even a country, it was just a bunch of little, kind of fiefdoms, pretty much continually at war. and he envisioned a united wales. this was 800 years ago. he was a remarkable man and through a combination of i think, probably good people skills and battle savvy and statecraft, he made it happen. he brought this group of warring lords together into a country, wales, and kept it together until he died, many many years. so one of the ways he did this was, he built castles. and one of the castles that he built was in a little town in north wales called criccieth. and now it's just a ruin, but if you kind of squint, you can kind of see how impressive it must have been, it's on a headline overlooking cardigan bay. so what i want you to do is come back with me in my time machine and stand by the ocean shore with llywelyn fawr, and we'll walk with him as he goes through this process that i just described to you. so w
