Bath Waters
Bath is going to be a spa again and the people who first made it a spa were the Romans. , The extensive engineering works which have been undertaken at Bath since 1979 to modernise and improve the thermal water supply for the new spa development, gave Professor
Cunliffe a unique opportunity to discover how the Roman engineers tackled the problems of controlling the hot springs nearly 2,000 years ago
In the five years since Chronicle first reported, continued excavations under the Pump Room have revealed the remains of a great Roman temple precinct dedicated to the goddess ot the spring, Sulis Minerva.
To be able to envisage this impressive
Roman complex from every angle,
Chronicle commissioned a computer model of it based on actual and projected measurements. The computer has produced pictures as clear as if the original Roman structures had been photographed.
