Staple Inn dates from the late 14th century, when it was one of London's Inns of Chancery, where the King's clerks worked. The Elizabethan front to the building was added in 1586.
The name Staple Inn comes from a previous use for the building as a wool-taxing house, where the quality or 'staple' of the wool was measured.
The Inn is now used as offices and is not open to the public. However, you can walk through the gateway between the shop front, to the 
quiet little garden that Charles Dickens described in his novel, The Mystery of Edwin Drood.
