If you head northwest from the Arch of Septimius Severus, you pass under the Oea Gate, or Arch of Antoninus Pius (2nd century AD). You eventually come to the superb Hunting Baths, recognisable by their consecutive, barrel-domed roofs in light sandstone. These baths never rivalled the Hadrianic Baths, but the frescoes and mosaics throughout the building are superb. The frigidarium contains the fresco that gave the baths their name - showing hunters and animals in the Leptis amphitheatre.
There are also some fine frescoes in the adjoining vaults. On the walls of the bath is an exceptional Nilotic fresco; watch out for the good marble panelling. The baths, constructed in the 2nd century AD, were used for almost three centuries.
