What many people don't know is Wales can lay claim to one of the oldest colleges in the world.
In 395 AD a college of priests called Cor Tewdws was founded at Llantwit Major.
Some say Cor Tewdws was the earliest school in Britain, and arguably the oldest college in the entire world. After the Romans left Britain in the early 5th century the college was left to defend itself against raiders, and in 446 AD Irish pirates burned the college to the ground.
One story says that St Patrick was kidnapped from Cor Tewdws by the pirates.
It also has a nice collection of Celtic stones that date from the 9th and 10th centuries
