Conan Doyle made 221b Baker Street the address of the famous detective. However, the numbering in the street stopped at 85. Thanks to new numbering in 1930, order has been restored. Built in 1815 and an hotel garni from 1860 to 1934, the building was redeveloped according to Sir Arthur Conan Doyle's descriptions. On display in the study are familiar objects associated with the famous detective, as well as old copies of the Times.
