Baths of Caracalla: the grandest ruin most visitors miss

The Baths of Caracalla were the second largest public baths of ancient Rome. They are a fifteen-minute walk from the Colosseum, and almost empty.

    Why the Baths of Caracalla is worth it

    The baths were built between about 212 and 216, begun under Septimius Severus and opened under his son Caracalla. The whole complex measured 337 metres by 328 and covered 25 hectares. It could take some 1,600 bathers at once, who came not only to wash but to exercise, read and talk: there were gymnasia, gardens and two libraries. They stayed in use for more than three hundred years, until the 530s.

    What is left is the brick core, stripped of its marble, and it is still overwhelming. The walls of the great halls stand to most of their height. You walk through them at ground level, on stretches of the original black and white mosaic, and for once in Rome you can feel the true size of an imperial building without a crowd in the way.

    The sculptures found here are now among the most famous in Italy: the Farnese Bull and the Farnese Hercules, both in Naples. The architects of the old Pennsylvania Station in New York took the baths as their model.

    What to see

    1. The central halls

      The cold room, the frigidarium, was the heart of the building, a hall under three vaults almost 33 metres high. The hot room, the caldarium, was round, 35 metres across.

    2. The mosaics

      Floors of marble and mosaic survive in the two exercise courts, and fallen pieces from the upper storey are propped against the walls.

    3. The gardens

      The baths stood in a walled garden with a running track. It is grass and pines now, and the best place to see the ruins whole.

    4. Summer opera

      In summer the Rome Opera sets its stage against the ruins and performs here in the open air.

    How to do it well

    • Come late in the afternoon, when the brick turns red and the shadows give the halls their depth.
    • It joins well with the Circus Maximus and the Aventine, both ten minutes' walk north.
    • Bring water and a hat. The site is open ground.
    • An audio guide or an app earns its place here: with the marble gone, the rooms need explaining.
    • From the Colosseum, walk down Via di San Gregorio and across the end of the Circus Maximus.
