Isca Silurum

Another amphitheater! This time a real ancient one:

It was built around 90 BC near the Roman legion camp in southern Wales. It could accommodate nearly 6000 spectators.

Not far from here is the second oldest building in the UK: Tintern Abbey, a monastery of the Cistercians, founded in 1131. In the 16th century, it was finally abandoned and completely deteriorated. Such a pity for such a structure!
