The green is secretly Stuart. 17th-century houses built on the former courtyard of Bath Priory were later given a Georgian facelift. Here the greenery has taken over. 200 years ago it seemed a good idea to soften Georgian symmetry with a hint of foliage. Plane trees were dotted around the city. Now architectural purists talk longingly about chainsaws, but artists reach for their palettes and tourists for their cameras.
