Odeon of Domitian
The Odeon of Domitian was an ancient Roman building on the Campus Martius in Rome, used for plays and musical competitions and with room for an audience of 11,000. Begun by Domitian in imitation of Greek odeons, it was completed or restored in 106 by Apollodorus of Damascus. The outline of its cavea is still preserved by the façade of the Palazzo Massimo alle Colonne, but the only actual remains is a cipoline monolithic column just in front of the Palazzo's rear façade.
