The Zappeio Roman Baths (Ρωμαϊκά Λουτρά Ζαππείου) are an archaeological site located in the eastern section of the National Garden of Athens, near the Zappeion Hall complex. Discovered during excavations in the 20th century, they represent a preserved fragment of Roman architectural and civic heritage in the heart of the modern Greek capital.

The baths date back to the Late Roman period (circa 3rd–4th century AD) and were likely used as public thermal baths — an essential part of daily life in Roman society. These facilities served not only hygienic purposes but also functioned as spaces for conversation, relaxation, and intellectual exchange.

The archaeological remains include sections of various functional rooms: the apodyterium (changing room), frigidarium (cold room), tepidarium (warm room), and caldarium (hot room), as well as parts of the hypocaust heating system and underground channels. While much of the structure has been lost over time, the layout and some features are still visible and recognizable.

The Roman Baths form part of an open cultural site, accessible to the public. They can be viewed during a walk through the Zappeion area and serve as a reminder of Athens’ layered history — a city shaped by classical, Roman, Byzantine, and modern Greek influences.

The Zappeio Roman Baths are not just an archaeological curiosity but a window into ancient communal life, where wellness, conversation, and architecture were intricately linked.
