🔦 Spotlight location: Caerleon

The Roman amphitheatre in Caerleon

Caerleon, known as Caerllion in Welsh and called Isca by the Romans, is a town rich in history and legend. The Roman heritage is hard to ignore, with fantastically well-preserved ruins of the Roman fortress and ancient amphitheatre. While it may be known best for its history today, the town is also associated with the mythical King Arthur... Could this be Camelot?!

On the Caerleon treasure hunt Trail, you'll weave your way through the fantastic Roman ruins, including the amphitheatre, fortress baths and barracks, and wander beside the River Usk while searching for the long-lost treasure. 

Fab facts and twisting tales

When Geoffrey of Monmouth wrote his History of the Kings of Britain in the 12th century, he named Caerleon as a very important city. Why? Well, because he believed this was the site of the legendary King Arthur's first court. He even suggested that the amphitheatre could be the remnants of the famous Round Table!

Caerleon is just one of the many places thought to be Camelot, though, with potential sites scattered from Cornwall to Scotland and even over in France. But, with so many retellings mentioning Caerleon by name, it's hard not to wonder...
