Thermal Baths of Neptune

Thermal Baths of Neptune

The thermal baths of Neptune, built along the Decumanus maximus in the harbour city of Ostia Antica, between the theatre and “Porta Romana” (Romana gate: main entrance on the city walls facing the city of Rome), date back to the time of emperor Hadrian (2nd century AD). 

A vast complex with a gymnasium, the proper baths (warm, hot and cold water), dressing rooms and common areas: entrance halls present two very well preserved mosaics, one representing Neptune drawn by seahorses, the other portraying his spouse Anfitrite surrounded by tritons. 

Thermal baths were heated with hot air circulating under the floor and along the walls through terracotta tubes, under the street level there were the furnaces that heated the warming system, operated mostly by slaves.
