Discovered: Britain's very own Colosseum

Archaeologists have discovered that what had been thought to be a relatively small, down-market amphitheatre in Britain was in fact a top-of-the-range, though admittedly more intimate, version of Rome's famous gladiatorial arena.

Indeed, this British Colosseum - in Chester - may well have been built as a replica of the one in Rome, possibly on the orders of the Roman Emperor Septimius Severus, who was in Britain at the time.

Although it was much smaller than the Colosseum, its outer wall appears to have had a blind arcade of 80 arches, giving it a superficially similar appearance to the one in Rome. If the archaeologists' calculations are correct, Rome and Chester were the only places in the Roman world to have amphitheatres with that number of arches.
