The Denmark Street was originally residential, but became used for commercial purposes in the 19th century. At first, metalwork was a popular trade but it became most famous as Britain's "Tin Pan Alley" housing numerous music publishers' offices. The street is situated in the area once known as St Giles’s, which was long a centre for the printing and distribution of ballad sheets, also known as broadsides. Denmark Street is still London’s prime location for the sale and repair of musical instrument.
