In brief
The historic environment combines ancient remains with later Palladian architecture.
Useful to know
Bath began as a Roman thermal center, but today's historical image includes a strong 18th-century layer. UNESCO lists neoclassical Palladian buildings combined with Roman baths. [1]
For an architectural comparison, take a look at the bathing complex and later urban spaces separately. Common place does not mean common date. Then look for how the facade rows form an ensemble beyond the single house. Bath is an example of how new town planning can have its own expression without the ancient layer disappearing from the narrative.
