Great Bath © Diego Delso
The Romans were the first to capitalise on the only natural hot springs in Britain, but it is believed that they were a local attraction long before the building of Rome. These ancient baths were once considered the finest in the Roman Empire, but in the middle ages fell into disrepair. It was not until a visit by the ailing Prince George in 1702 that the baths once again became a popular healing destination. Over the course of the city of Bath's redevelopment in the late 18th century, the Roman ruins were rediscovered and restored. Today, visitors can see the seven ancient baths and view the Georgian splendour of the Pump House, where the musty mineral waters can be sampled by the strong of stomach. The magnificent centrepiece is the Great Bath. Lined with lead and filled with hot spa water, it once stood in an enormous barrel-vaulted hall that rose to a height of 131ft (40m). For many Roman visitors, this may have been the largest building they had ever entered in their life.
