Reflecting the perfect blend of Roman style and creativity, Roman Baths at Carthage are among the most popular tourist attractions in Tunisia. Also known as Antonine Baths or simply as Antonine Bath Complex, it was built somewhat between 146 and 162 AD. Though named in the memory of Antoninus Pius (the fifteenth Roman emperor and the fourth among the Five Good Emperors), the construction of the complex was actually started by his father Emperor Hadrian.

However much of the Ancient Roman Baths at Carthage is destroyed but what remains presently itself gives an impression of unique design and sheer size of the complex. Laced with all the must features of a typical Roman bath complex, Antonine Baths were located on the shore of Carthage. Water was supplied with the help of Borj Jedid cisterns that were fed from the watered sources of Zaghouan Mountains through aqueducts.

As per archeological study of the ruins, it is estimated that the complex features an open air pool with sun terrace, two sets of communal lavatories in semi-circular forms, area for exercise and separate warm and hot rooms, as well as a central cold room. Separate bathing facilities for men and women were designed.

But what makes Carthage Roman Baths unique from others is its large parameters. The central frigidarium or the cold room was a vast structure with dome and measured about 22m x 47m. Its dome was supported with the help of 8 grey granite massive columns topped with marble capitals. Each marble capital weight around four tons. Along with outdoor pools, there are multiple inside too, the largest among them was a modern Olympic swimming pool.

The whole complex of Ancient Roman Baths Carthage was divided into three layers- basement, ground floor and upper floor. As per the evidences, basement consisted of the hypocausts, water supply and store rooms while the ground floor houses rooms for the staff members. The upper floor of the complex had bathing facilities. But with changing time, much of the structure has been changed into just ruins. Whatever was the design and uniqueness was attached with the complex, Carthage Roman Bath Complex was the largest outside Rome.
