The Theatre Royal, Drury Lane, commonly known as Drury Lane, is a West End theatre and Grade I listed building in Covent Garden, London, England. The building faces Catherine Street (earlier named Bridges or Brydges Street) and backs onto Drury Lane.  The building is the most recent in a line of four theatres which were built at the same location, the earliest of which dated back to 1663, making it the oldest theatre site in London still in use.[1] According to the author Peter Thomson, for its first two centuries, Drury Lane could "reasonably have claimed to be London's leading theatre".[2] For most of that time, it was one of a handful of patent theatres, granted monopoly rights to the production of "legitimate" drama  in London (meaning spoken plays, rather than opera, dance, concerts, or plays with music).
