The museum houses artefacts from the Roman period including objects that were thrown into the Sacred Spring, presumably as offerings to the goddess.
These include more than 12,000 Denari coins, which is the largest collective votive deposit known from Britain.
A gilt bronze head of the goddess Sulis Minerva, which was discovered nearby in 1727, is displayed.
An audio guide is available in 12 languages.

The Bath Roman Temple stood on a podium more than two metres above the surrounding courtyard, approached by a flight of steps.
On the approach there were four large, fluted Corinthian columns supporting a frieze and decorated pediment above.
The pediment, parts of which are displayed in the museum, is the triangular ornamental section, 26 feet (7.9 m) wide and 8 feet (2.4 m) from the apex to the bottom, above the pillars on the front of the building.
It featured the powerful central image of a possible "Gorgon" head glowering down from a height of 15 metres (49 ft) on all who approached the temple.
The great head itself has snakes entwined within its beard, wings above its ears, beetling brows and a heavy moustache although there is some controversy about what this really represents, as Gorgons are usually female.
An alternative interpretation sees the central head as the image of a water god such as Oceanus, and yet another as a Celtic sun god.
 In early 2010 various stones on the pediment were conserved and rearranged.

Also on display are the remains of the elaborate hypocaust heating system, which served the sweat rooms.

In 2016 planning permission was received for a new learning centre aimed at schoolchildren and linked to the baths by a tunnel.
Funding is being sought from the Heritage Lottery Fund and, if successful, it is hoped the centre will open in 2019.
