Temple of Hadrian

The Temple of Hadrian was built in 145 AD by Emperor Antoninus Pius, successor of the deified Hadrian, to whom the temple was dedicated. The temple was situated at the Campus Martius (Field of Mars).

A large staircase led to the four meter high podium. On the podium was a cella, surrounded by 48 large Corinthian columns, each 15 meter tall. Along the length of the temple were 13 columns, the other sides had 8 columns. A small flight of stairs led to the cella, a barrel vaulted chamber decorated with pilasters. At the foot of the pilasters were war trophies and reliefs depicting conquered provinces. Some of the reliefs can now be found at the inner court of the Capitoline Museums.

A part of the cella's wall, which was made of a special kind of volcanic tuff, can still be seen behind the remaining columns.

Only 11 columns have survived the times, all were part of the north side of the temple.

At the end of the 17th century pope Innocent XII commissioned Italian architect Carlo Fontana with the construction of a new papal customs office at the site of the Temple of Hadrian. Fontana, who worked with his son Francesco on the project, integrated the remaining columns of the temple in the new building, which was completed in 1700 after 10 years of construction.

Today the building houses the Borsa Valori di Roma, Rome's stock exchange. It is located at Piazza di Pietra, a small square not far from the Via del Corso.
