The Roman Baths are at the heart of the World Heritage Site and when the new Thermae Spa opens this year the city's naturally hot springs will once again be available to the public.

In Roman times Bath was called Acqua Sulis and the Romans decided to build some baths here, where they could bathe around Britain's only natural hot spring. Here over a million litres of mineral water rises each day at a temperature of over 46C.

The baths are nearly 2,000 years old, built next to a hot spring, served many pilgrims visiting the Temple of Sulis Minerva.

The extensive ruins and treasures from the spring are beautifully preserved and presented in the museum. You can also see the Roman head of Minerva, the goddess of the spring, plus many items of sculpture, jewellery and even personal messages to the goddess.

Inside the Pump Room there is now a restaurant where you can take morning coffee, lunches and teasand sample the hot spa water which still comes up from 3km below ground.

During the summer months there are also special twilight tours of the baths.

The new Thermae Bath Spa is finally expected to open this year and will mean the city is a spa town once again. It will be the only natural thermal spa in the country.
