Want to visit the brothels where the most famous writer in the world got drunk? There's an app for that.
Designed by former Guardian journalist Victor Keegan, the app uses the iPhone's geonavigation tool to guide Londoners and London visitors to some of the Bard's favorite former haunts. There's the Globe theater, of course, but Keegan also directs fans to more obscure, long-destroyed landmarks where modern office buildings now stand. So while you may not be able to have a pint at the Falcon Inn, the Swan theater-adjacent pub where Shakespeare almost surely drank, you can still take a picture next to the plaque that commemorates its existence.
Accompanying the location markers are thoroughly researched informational sidebars. Thus, you won't just stand in front of where The Elephant used to be, you'll also know that it was "an inn and former stew house (brothel)," and that Shakespeare referenced it in Twelfth Night—behold, Elizabethan product placement.
