When recently reading Dickens's description of Dr. Manette's residence in "A Tale of Two Cities" , I found in the notes to my edition (B&N Classics) the following: "A replica (of 'The Golden Arm') hangs above a residence in what is now Manette Street in Soho". (See also: Part of additional adjacent buildings that they also acquired in Manette Street was the site of the Old Goldbeater's House. )
So it appears that the name of that particular street in London was changed to Manette Street to commemorate Dickens's memorable Manette family of that novel. This struck me as quite unusual: Naming streets and buildings to memorialize people who actually lived is of course commonplace, but I don't recall ever hearing of a street being named after a fictitious character from a novel as an attestation that said location was the place where something fictional occurred.
Was/is this practice commonplace in England or Europe, or is London's Manette Street something exceptional: A great testimony to how beloved and believable Dickens's writings and characters were to the British.
Edit (and change of question title) in reference to the answers:
Several have mentioned clever, catchy naming schemes of places referring to fictional characters, but have no real connection to the fictional characters. The uniqueness of Manette Street is that it's designating a real place on the map as the site of the residence of fictional characters. i.e. - By calling it "Manette Street" they were essentially saying "This is where it happened", although the story is fiction.
