221B Baker Street

221B Baker Street was the fictional address of Sherlock Holmes and Doctor Watson in London, England. Located in a multistory building, this was the residence of Holmes in the 1890s. It included a sitting room where Holmes kept objects of significance to him. The furniture in this room was of the Victorian era.

In early 2365, aboard the USS Enterprise (NCC-1701-D), this sitting room was recreated for a holodeck program used by Data and Geordi La Forge.
