The Red Bull was a playhouse in London during the 17th century. For more than four decades, it entertained audiences drawn primarily from the northern suburbs, developing a reputation for rowdy, often disruptive audiences. After Parliament closed the theatres in 1642, it continued to host illegal performances intermittently, and when the theatres reopened after the Restoration, it became a legitimate venue again. It burned in the Great Fire of London, among the last of the Renaissance theatres to fall.
Less is known of the Red Bull's provenance than of other contemporary venues such as the Globe Theatre and Fortune Theatre. It was constructed in 1604 on St John Street in Clerkenwell; court documents reveal that it was built by renovating an inn with a central square. This origin accounts for its square floor plan, a design shared only by the original Fortune among period playhouses. It may have been named for cattle that were driven down St John Street toward the markets at Smithfield.
Apart from these few facts, little is known of the theatre's particulars. Scholars assume that it was roughly the same size as the Globe and Fortune, its competitors; at least in its early decades, its companies offered credible competition to the King's Men and Prince Henry's Men. W. C. Lawrence argued that the theatre was roofed over in the early 1620s, but his arguments were largely refuted by Leslie Hotson and G. E. Bentley. The Red Bull was most likely similar to the other outdoor theatres against which it competed, with an uncurtained thrust-forward stage backed by a tiring house and balcony, surrounded by standing room, and overlooked by galleries on three walls. Its occupancy was perhaps slightly less than the nearly 3,000 of the Globe.
There is no documentary proof that the Red Bull was occupied before 1607, when Queen Anne's Men are known to have performed there; however, court records show that the theatre was built in 1604, and references in the royal patent for the venue mention Thomas Greene, comedian of the Queen's company, suggest it was built for that troupe. In addition to Greene, Martin Slater, Aaron Holland (a servant of the Earl of Devonshire as well as a Queen's Man), and Thomas Swinnerton were involved in the planning. Perhaps because they had learned from Philip Henslowe's recent problems with neighbourhood opposition in building the Fortune, they did not approach the court for approval until they had already placated their parish neighbours—as Henslowe had—by contributing liberally to poor relief.
