The preservation and extensive excavations at Ostia Antica have brought to light 26 different bath complexes in the town. These range from large public baths, such as the Forum Baths, to smaller most likely private ones such as the small baths (I, XIX, 5). It is unclear from the evidence if there was a fee charged or if they were free. Baths in Ostia would have served both a hygienic and a social function like in many other parts of the Roman world. Bath construction increased after an aqueduct was built for Ostia in the early Julio-Claudian Period. Many of the baths follow simple row arrangements, with one room following the next, due to the density of buildings in Ostia. Only a few, like the Forum Baths or the Baths of the Swimmers, had the space to include palestra. Archaeologist name the bathhouses from features preserved for example the inscription of Buticoso in building I, XIV, 8 lead to the name Bath of Buticosus or the mosaic of Neptune in building II, IV, 2 lead to the Baths of Neptune. The baths in Ostia follow the standard numbering convention by archaeologists, who divided the town into five regions, numbered I to V, and then identified the individual blocks and buildings as follows: (region) I, (block) I, (building) 1. Regio I Forum Baths The Forum Baths (I, XII, 6) are located of the Via della Forica south of the Forum. The complex is also called the Thermae Gavii Maximi, named after Marcus Gavius Maximus, the praetorian prefect who sponsored their construction. The baths were intended for public use in Ostia Antica and covered c. 3,200 square meters. Statues of Hygieia, Aesculapius, and Fortuna were some of the many statues recovered from the bath that most likely belonged to the Forum Bath's decorative program. Additionally, cipollino columns were used to decorate the bathhouse. There were several phases of construction for the baths. The Forum Baths were initially built during the reigns of Emperor Antoninus Pius c. 160 C.E. with subsequent additions during the Severan Dynasty (193-225 C.E.), reign of Maxentius and Constantine (306-337 C.E.), and finally during the reign of Theodosius (379-395 C.E.). The Baths were constructed in the city center and were the largest of all Ostia baths with a large palaestra south of the main building. The Forum Baths are characteristic of the experimental mode of planning during Hadrianic-Antonine period.
