Britain has many beautiful cities, but Bath is the belle of the ball. The Romans built a health resort to take advantage of the steaming-hot water bubbling to the surface here; the springs were rediscovered in the 18th century and Bath became the place to see and be seen in British high society. Today, Bath's Georgian architecture of sweeping crescents, grand town houses, and Palladian mansions (not to mention Roman remains, a beautiful abbey and a 21st-century spa) make the former home town and inspiration of novelist Jane Austen a must.
