For hundreds of [?], small groups of people visited the hot springs at what we now call Bath, but no permanent [?] were built there until the Roman period. When the Romans invaded Britain (around 43 A.D.), they heard of the [?] hot springs and, like the Celts, they also established a sacred site there: they built temples and baths for people to [?] in the hot water. After the Romans left Britain, their buildings were no longer used and so they became [?]. In later [?], people continued to visit the hot springs at Bath, and many stayed there to live and work, but it was not until the 18th century that Bath became very [?] and grew into the kind of city it is today.
