After the eleven-year-long Puritan Interregnum, which had seen the banning of pastimes regarded as frivolous, such as theatre, the English monarchy was restored to the throne with the return of Charles II in 1660. Soon after, Charles issued Letters Patent to two parties licensing the formation of new acting companies. One of these went to Thomas Killigrew, whose company became known as the King's Company, and who built a new theatre in Drury Lane. The Letters Patent also granted the two companies a shared monopoly on the public performance of legitimate drama in London; this monopoly was challenged in the 18th century by new venues and by a certain slipperiness in the definition of "legitimate drama," but remained legally in place until 1843. The new playhouse, architect unknown, opened on 7 May 1663 and was known from the placement of the entrance as the "Theatre Royal in Bridges Street." It went by other names as well, including the "King's Playhouse." The building was a three-tiered wooden structure, long and wide; it could hold an audience of 700. Set well back from the broader streets, the theatre was accessed by narrow passages between surrounding buildings.
