The Roman Theatre is an ancient Roman theatre in Cartagena, Spain.
The theatre was built between 5 and 1 BC, as it has been proven by the dedication of the edifice to Gaius and Lucius Caesar, grandsons of Augustus, who had designated them as his successors.
In the 3rd century AD a market was built over the theatre, reusing its materials, with a semicircular open space which followed the plan of the orchestra. The market was perhaps abandoned after a fire caused by the Vandals in 425. A market quarter of the Byzantines was established on the site in the 6th century AD.
During the 13th, over the upper cavea was built the Old Cathedral of the city. In 1988 the first remains of the theatre were discovered in occasion of the construction of the Centro regional de artesanía. The archaeological excavations and the restorations were completed in 2003. In 2008 a museum, designed by Rafael Moneo, was opened.
The cavea was carved directly on the rocks in its central part, and tops a series of vaulted galleries. It had a capacity of some 6,000 spectators. It was divided horizontally in three parts (ima, media and summa cavea), in turn divided into radial sectors by the staircases (five in the upper part, seven in the medium and upper ones).
The public entered from two side passages (aditus), where the dedications have been found. The orchestra had a semicircular plan and housed three rows of wooden seats for the authorities (proedria). The stage (proscaenium) had a length of 43.60 m. The scaenae frons had three semicircular exedras and decorated by two orders of columns, with bases and capitals in Luni's marble, and shaft in pink travertine of Mula. The stage edifice had a total height of 14.60 m. It have been found three round altars dedicated to the Capituline Triad and to the divinities of Apollo (Graces, Muses and Horae), as well as a statue of Apollo with lyre and one of Rhea Silvia.
Behind the stage building was a portico (porticus post scaenam) with a double porticoed gallery revolving around a central room housing a garden.
