Visitors to Bath's Roman Baths will encounter costumed characters known from archaeological evidence to have visited the site.
Characters discuss the latest treatments offered by the spa
Some of the characters already feature on the museum's award-winning children's audio tour.
They include Peregrinus, a traveller from Trier in the Rhineland, sculptor Sulinus and his father Brucetus.
They can be heard discussing building techniques and some of the 'newer' ideas brought in by Roman architects.
