In the Pietra square (piazza di Pietra), included in the north wall of the edifice of the money (stock exchange), there are the ruins of the temple of the Divo Adriano. Built by Antonio Pio, in 145 d.c. in honour of Adriano, on via Lata, in the Campo Marzio, it was accessible by means of the triumphal arch : it was erected in the interior of a square surrounded by porches with columns in travertine.



A long frontal flight of steps lead to the top of the podium (platform) over which rose eight corinthian marble columns, high 15 m. and with a diametre at the base of 1.44 m.
Behind the six central columns there was a large space, deprived of the support of columns, preceeding the cell : to this one was reaching by means of a few steps.
The interior space, rectangular but with long walls articulated by five semi-columns and two pilasters and the short one opposite to the entrance with four semi-columns, was covered with barrel-vault in opus coementicium. The wall of the cell was in peperin and covered with marble slabs as it is seen by the presence of clamping holes. The edifice moreover signalizes itself not only by the floreal decoration already assimilated to the asiatic models imported by Adrian, but also for its distinct vertical sense which will find a complete application in the last quarter of the second century with Settizonio on the Palatino Hill.
