The Hadrianeum in Rome lay in the Campus Martius on the west side of the Via Lata, to the south of the Ara Pacis. Parts of the temple can be seen along one side of the Piazza di Pietra. Eleven Corinthian columns, made of Proconnesian marble, as well as the north side of the cella are incorporated into the Borsa.
There is no epigraphic evidence to confirm the identity of the temple although Antoninus Pius dedicated one to him in this area in AD 145; this is the most likely interpretation for this structure.
A series of 24 reliefs cut from Proconnesian marble have been associated with the temple. They were probably incorporated on the cella. The figure shown here, holding a vexillum, probably represents the province of Mauretania. The relief showing shields and an axe probably represent trophies.
