The baths were known in 532 (Crow et al., 2008, p. 10). Theophanes records that the baths were burned during the Nika riots. It was situated near the praetorium and the Hospice of Euboulos and probably to the north of Hagia Eirene (Janin, 1964, p. 216).
They can possibly be identified with the bathhouse and cisterns behind the site of the Archaeological Museum (G6/5, 7, 9). Their altitude between 20-40 m above sea level indicates that they were supplied by the Hadrian Waterway (Crow et al., 2008, p. 124). See also Müller-Wiener, 1977, p. 49-50.
