This was once the largest thermal baths from antiquity in all of Africa and one of the three largest in the entire Roman empire. But, they are very much ruins now. It is certainly impressive. And, to be honest, ruins on this scale with the Mediterranean background are just stunning. When you visit, don't miss the old crypt right behind the ticket booth - or nearby. It is some beautiful mosaics.

This was excellent, I wasn’t expecting there to be much more than a few knee high stones left in Carthage, but these old baths cover a large area right by the sea and are a storey high. You can walk through them all and I was really impressed, it was a much more substantial site than I was expecting in Carthage. It’s the best of the sites to see in Carthage

A truly impressive archaeological site from the Roman era that can give a hint of the greatness and power of the Roman Empire. Water was brought to this place by an aqueduct built on the Zaghouan mountains, 139 km away. Baths are built meticulously, reflecting engineering excellence and superior design skills. As the largest set of Roman thermae built on the African continent and one of the three largest built in the Roman Empire, the Antonine Baths were a huge Roman bath complex in ancient Carthage here in Tunisia. Built between 146 and 162AD, it was started in the reign of Emperor Hadrian and completed under his successor Antoninus Pius, after whom the baths were named. The baths could cater for a multitude of visitors and contained a number of rooms and chambers standard to such ancient bath complexes, including the Frigidarium (cold room), Caldarium (hot room) and Tepidarium (hot bath). There was once also an enormous seaside swimming pool as well as a Gymnasium for physical activity. The baths were destroyed by the Vandals in 439 AD, and the stone was reused by the Arabs during the construction of Tunis. Today, the ruins are relatively well-preserved.

A lot of the archeology in Carthage has been butchered, overtaken by modern villas and concrete. Thankfully, the Baths of Antoninus are an exception. They are enormous ; as a matter of fact they were largest set of Roman thermae built on the African continent and one of three largest built in the Roman Empire. As part of he Roman hydraulic complex that brought water 132kms from Zaghouan to Carthage, they are a wonder of engineering as well. And they're easily accessible, so it's important to spend a couple of hours here.

Very impressive. The history. The setting is beautiful too. Be prepared to be blown away. Walk, explore and learn. I went early but it was still very hot. There was a slight breeze. There are toilets when you exit. If you are not with a guide, then take a guide book as there is very little information.
