To the east of Rome's Jewish Ghetto, the Teatro di Marcello is the star turn of the dusty Area Archeologico del Tearo di Marcello e del Portico d'Ottavia. A 20,000-seat mini-Colosseum, the theatre was planned by Julius Caesar and completed in 11 BC by Augustus who named it after a favourite nephew, Marcellus. In the 16th century, a palazzo, which now contains several exclusive apartments, was built on top of the original structure.
