Thermae Portus Marinae
About
A large bath complex just outside Ostia's Porta Marina gate, built to catch sea breezes on the road out toward the beach. Trajan broke ground around 110 CE, but construction dragged on through Hadrian's whole reign and wasn't dedicated until 138 or 139. It was still an active building site when Trajan died in 117.
What happened here
The furnaces are lit before dawn and the water is hot by the eighth hour, which is when the town arrives. The circuit is a habit: undress and hand your clothes to an attendant who may or may not be watching them, exercise in the courtyard, sweat in the hot room, scrape the oil and dirt off with a curved bronze strigil, then the warm pool and the cold plunge. Entry costs a coin small enough that almost nobody is priced out, and on a benefactor's birthday it is free. There is food, drink, ball games, gambling, hair-plucking, business and shouting; a writer complaining about the noise from the flat above is complaining about all of it. Men and women bathe at different hours, or in separate wings.
