Planned for several years and rumored for at least four, Apple has reportedly confirmed that it will build a retail store along historic and picturesque Princes Street in Edinburgh (Scotland), in the shadow of a castle that dates to the 12th century. The Edinburgh Journal wrote last month that Apple was in final negotiations with the city, probably over how much preservation would be required of a heritage building, and how much of Apple’s brand could be displayed at the storefront. Now the newspaper says that the discussions have been finalized, but did not say exactly where the store will be located. However, speculation has focused on current construction at 122-123 Princes Street, including the complete demolition of 121 and renovation of 123. The city’s planning department has approved plans for a retail-hotel project, but has withheld the usual architectural drawings from its Web site. City parcel maps show that 122 Princes Street is 52 feet wide and 125 feet deep, creating a possible 13,000 square-foot retail space on the ground floor and basement. That amount of space is consistent with a street-level Apple store. Based on the current state of construction, if #122 is the location, the store would open in late 2011.
