A different model was developed with the Blackfriars Theatre, which came into regular use on a long-term basis in 1599. The Blackfriars was small in comparison to the earlier theatres and roofed rather than open to the sky. It resembled a modern theatre in ways that its predecessors did not. Other small enclosed theatres followed, notably the Whitefriars (1608) and the Cockpit (1617). With the building of the Salisbury Court Theatre in 1629 near the site of the defunct Whitefriars, the London audience had six theatres to choose from: three surviving large open-air public theatres—the Globe, the Fortune, and the Red Bull—and three smaller enclosed private theatres: the Blackfriars, the Cockpit, and the Salisbury Court. Audiences of the 1630s benefited from a half-century of vigorous dramaturgical development; the plays of Marlowe and Shakespeare and their contemporaries were still being performed on a regular basis, mostly at the public theatres, while the newest works of the newest playwrights were abundant as well, mainly at the private theatres.
