Since one of London's top tourist attractions appeared in Dan Brown's Da Vinci Code, tour guides have been inundated with questions from curious tourists. In an effort to help them counter the factual errors in the book, tour guides at Westminster Abbey were given information sheets, reported the Press Association.

The factual errors identified in the best-selling novel regarding the abbey include mentions of metal detectors, which don't exist, a claim that Alexander Pope delivered the eulogy at Isaac Newton's funeral, and the assertion that visitors can carry out brass rubbings.

The Dean and Chapter of Westminster Abbey condemned the novel as "theologically unsound."

The abbey has already refused permission for a film based on the book to be shot on the premises. Lincoln cathedral, however, is reported to have accepted £100,000 for film, which will star Tom Hanks.
