The Baths of Caracalla in the south-east angle.

In a closer sight .

Detail of the inner courtyard.

A farther view allows us to see better the connection of the Aqua Antoniniana that supplied the Baths on the left of the picture. The road going behind the Baths is the Via Ardeatina that ends near the Circus Maximus.

The Via Ardeatina went over the hillock between the Baths of Caracalla and the Aurelian Wall. As it often happened, some Mausoleums were built alongside the Roman roads and ornamented the landscape.

In front of the endless façade of the Baths, the Via Nova was running parallel to the Via Appia which you can see in the foreground.
