Cirencester's Corinium Museum owes its existence, in part, to a burst sewer. When workmen digging drains in 1849 struck two Roman mosaics, the 4th Earl of Bathurst decided the town needed somewhere to keep them, and the museum was born.

It has been filling up with treasures since. Cirencester was Corinium Dobunnorum to the Romans, second largest town in Roman Britain after Londinium, and its workshops turned out some of the province's finest mosaic flooring. Star of the collection is the Hare Mosaic, unearthed in 1971, so beloved that Cirencester adopted the hare as one of its symbols.

VoiceMap's Cirencester Walking Tour, led by guide Owen Bowles, uses the museum's mosaics to trace Corinium's rise as Roman Britain's second city, while a tour through nearby Bibury sends walkers back to its cabinets to see coins and pavements pulled from a Roman villa in a bend of the River Coln.
