St Giles' Cathedral
Royal Mile Edinburgh EH1 1RE
Set right on the Royal Mile, dominating Parliament Square, 15th century St Giles offers an insight into Scotland's turbulent religious history, though it's also home of various cultural memorials including one to Robert Louis Stevenson and a stained glass window dedicated to poet Robert Burns. Don't miss the intricate carved woodwork of the small Thistle Chapel in the southeastern corner.
