What Travellers Say
Reviews Summary
Visitors find the Baths of Porta Marina to be a well-preserved and historically significant part of Ostia Antica. The intricate floor mosaics, particularly the depictions of athletes and marine life, are consistently praised for their beauty and detail. While the site is extensive, some visitors note that the exit route can be a bit confusing.
"The tour is nice but you have to go back than to the entrance. I hoped there will be some exit because there is a gate."
Barbora Doležalová
"No crowds."
Karl Enright
"The Terme della Marciana, also known as the Terme di Porta Marina, were built in the Trajan era and owe their name to the portrait of Marciana, sister of the emperor Trajan, found inside them.
A public thermal complex of this size takes time to build, so much so that its construction was almost certainly completed in the post-Hadrianic era. On the other hand, Trajan, Hadrian and Antoninus Pius were the emperors who spent the most on the urban modernization of Ostia.
In the place it is possible to see a large courtyard surrounded by a colonnade with a gymnasium function and a thermal sector located on a raised floor. Looking to the left at the remains of the apsidal pool, added in the 3rd century AD, it is possible to see the apodytherium (the changing room), where the floor is covered with a wonderful black and white mosaic depicting athletes.
The room in front of the apsidal pool was instead the frigidarium (cold baths): its floor is covered with a polychrome mosaic. On its right side there is an interesting mosaic with black and white tiles with a marine theme.
All the floor decorations have details and particulars to observe carefully.
The thermal complex remained in operation until the 5th century."

The History and Construction of the Baths
The complex was designed to serve the bustling port city of Ostia for centuries, remaining operational until the 5th century AD. This longevity is a testament to the enduring vitality of the neighborhood and the Roman commitment to public health and leisure. The baths were strategically located near the coast, a reminder of Ostia's historical connection to the Tiber River before its course shifted.
Architecturally, the Baths of Porta Marina featured a large courtyard surrounded by a colonnade, serving as a gymnasium or palaestra. Adjacent to this was the thermal sector, often situated on a raised floor. The evolution of the complex is evident, with additions like the apsidal pool in the 3rd century AD, showcasing ongoing modifications and expansions to meet the needs of the populace over time.
Discovering the Exquisite Mosaics
Adjacent to the apodyterium lies the frigidarium, or cold baths. Its floor is adorned with a polychrome mosaic, showcasing a richer palette of colors. Adding to the visual appeal is an adjacent room featuring an interesting black and white mosaic with a marine theme, complete with depictions of sea creatures and aquatic elements. These mosaics are not merely decorative; they are intricate works of art that provide valuable insights into Roman craftsmanship and artistic sensibilities.
These floor decorations are characterized by their fine details and require careful observation to fully appreciate their complexity. The marine theme, in particular, connects the baths to Ostia's identity as a vital port city. The preservation of these mosaics over centuries is a significant archaeological achievement, allowing modern visitors to connect directly with the aesthetic and cultural values of ancient Rome.
