View of the exterior of the 4,000 seat theater at Ostia. The road in the lower left is the Decumanus Maximus (Via Ostiense). Agrippa, the son-in-law of Augustus built the theater in the first century A.D. Additional work was done on the Theater during the reigns of Commodus, Septimius Severus, and Caracalla (late third century A.D.).
There were a few tabernae built in the exterior of theater—and nearby as well.
