Roman Spring Roman Baths

Roman engineers surrounded the hot Spring with an irregular stone chamber lined with lead. To provide a stable foundation for this they drove oak piles into the mud. At first this reservoir formed an open pool in a corner of the Temple courtyard but in the second century AD it was enclosed within a barrel vaulted building and columns and statue bases were placed in the Spring itself. Enclosing the Spring in a dimly lit building in this way and erecting statues and columns within it must have enhanced the aura of mystery that surrounded it. Offerings were thrown into the Spring throughout the Roman period.

Eventually the vaulted building collapsed into the Sacred Spring itself. We do not know when this was, but it is likely to have been in the sixth or seventh century. The oak piles sunk into the mud two thousand years ago continue to provide a stable foundation for the Roman reservoir walls today.
