Theatre of Marcellus

Is it worth the trip?

Yes, as a stop on foot rather than as a destination of its own. You cannot go in, so the visit is the outside of the building, and that is enough: an ancient theatre wall with a palace grown on top of it shows at a glance how Rome lived on in its ruins. With the temple columns, the Porticus Octaviae and the walk out to the Pons Fabricius, it makes an unhurried free hour beside the old Jewish quarter. In summer the area round the theatre is used for small concerts (en.wikipedia).

Getting there and what it costs

The nearest mapped bus stops, Piazza Monte Savello, are about 110 m from the theatre, and a paid car park is about 80 m away (OpenStreetMap). OpenStreetMap marks the archaeological area as wheelchair accessible.

There is nothing to pay. Roma Capitale’s tourism site gives the building as visible only from outside and lists no charge or opening hours for the archaeological area around it (Turismo Roma, read 16 October 2026). The Pons Fabricius is still a working bridge (en.wikipedia). San Nicola in Carcere is a working church; the city’s tourism site publishes no hours for it and refers visits to the temple remains underneath to a telephone booking line (Turismo Roma).

History

Julius Caesar cleared the ground for a theatre to rival Pompey’s, demolishing temples on the site, but was killed before it was built; Augustus bought more land and built a larger theatre (en.wikipedia; it.wikipedia). It was in use by 17 BC, when part of the Secular Games was staged there (en.wikipedia; it.wikipedia), and was named after Marcus Claudius Marcellus, Augustus’s nephew and intended heir, who died young (en.wikipedia; Turismo Roma). Published dates for its inauguration run from 13 to 11 BC (en.wikipedia; it.wikipedia; Turismo Roma; Pleiades).

It was the largest theatre in ancient Rome (en.wikipedia). Published figures for its diameter run from 111 to 130 m, and estimates of its audience from 11,000 to 20,000; a catalogue of the late 4th century recorded 17,580 seats (en.wikipedia; it.wikipedia; Turismo Roma). It is built of tuff and concrete faced in travertine, and is the earliest dateable building in Rome to use fired brick (en.wikipedia). Its stage building, restored several times, is entirely lost and known from the Severan marble plan of the city (it.wikipedia).

Vespasian and Alexander Severus restored it (it.wikipedia; Turismo Roma). By the late 4th century it was being quarried, its travertine probably going into the rebuilt Pons Cestius in 370, though its statues were still restored in 421 (en.wikipedia; it.wikipedia). In the Middle Ages the Fabi and then the Pierleoni made it a fortress, which saved it from further destruction; in the 16th century Baldassarre Peruzzi built a palazzo on the arcades, for the Savelli according to it.wikipedia and the city’s tourism site, and the Orsini owned it later (en.wikipedia; it.wikipedia; Turismo Roma). By the 1920s the arches were buried about 4 m deep; the city bought the ancient part and cleared and restored it between 1926 and 1932 (it.wikipedia; Turismo Roma).

The neighbours are older. The cult of Apollo was here by the mid-5th century BC, and his temple was rebuilt by Gaius Sosius, probably from 34 BC (en.wikipedia). The Temple of Bellona was vowed in 296 BC (it.wikipedia). The Forum Holitorium temples date from the 3rd and early 2nd centuries BC (it.wikipedia; en.wikipedia, San Nicola in Carcere). The Porticus Octaviae replaced the portico Metellus built after his triumph of 146 BC; it burned in AD 80 and 203 and was restored each time (Pleiades), and from the Middle Ages until 1885 its gateway sheltered the city’s fish market (it.wikipedia).
