Roman Baths, Bath

A remarkably well-preserved Roman bathing complex built around natural hot springs, with the steaming green Great Bath at its centre, surrounded by Georgian buildings. The museum shows the temple, curses written on lead tablets, and the gilded head of the goddess Sulis Minerva.

The water is not for bathing, but you can swim in the modern Thermae Bath Spa nearby, with a rooftop pool. Bath is a UNESCO World Heritage city of honey-coloured Georgian terraces; see the Royal Crescent, the Circus, Pulteney Bridge and Bath Abbey. Book the Baths online.
