2. Bath, UK
The historic city of Bath in England's west country was founded on hot springs, with the Roman Baths constructed around 70AD.
Today steam continues to rise from the baths, which are one of the best preserved Roman remains in the world. More than one million litres of steaming spring water still fill the bathing site every day. While the Romans believed this was the mystical work of the gods, we now know this water fell as rain water around 10,000BC.
In the 21st century, spa-goers can make the most of Thermae Bath Spa's facilities with a beautiful rooftop mineral-rich pool overlooking the city.
