Theatre of Marcellus

The Theatre of Marcellus (Teatro di Marcello / Theatrum Marcelli) is an ancient Roman open-air theatre located in the modern Rione Sant'Angelo of Rome. Construction was begun in the late Roman Republic under Julius Caesar and completed by Augustus (sources cite completion in the years 11 or 13), and the theatre was dedicated in the name of Marcellus. Architecturally it featured a semicircular orchestra, stage structures supported by columns, an exterior arcade with Doric and Ionic half-columns, radiating walls, and concrete vaulting typical of Roman theatre construction. In the early 16th century the surviving structure was partly incorporated into a palazzo for the Savelli family; the present palazzo work is attributed to Baldassare Peruzzi. The site has remained a visible ruin and an object of antiquarian, architectural, and tourist interest into the modern era and is used for cultural events such as contemporary summer classical concerts. Modern descriptions and guides note seating capacity estimates and its prominence in the urban fabric of Rome, though some capacity and superlative claims derive from secondary tourist summaries.
