Thermae Bath Spa is Britain’s only natural thermal Spa and benefits from the warm, mineral-rich waters which the Celts and Romans enjoyed over 2,000 years ago. Located in the heart of the World Heritage city of Bath, Thermae is a remarkable combination of five historic buildings and the contemporary architecture of the New Royal Bath. Highlights include the open-air rooftop pool with wonderful views over the city of Bath, the flowing curves of the Minerva Bath, the multi-sensory Wellness Suite and a choice of over 50 spa treatments and packages.
