The Royal Mile is the popular name for the succession of streets which form the main thoroughfare of Edinburgh's Old Town.
The Royal Mile runs from Edinburgh Castle at the top of the Castle Rock down to Holyrood Abbey. It is also known as “The High Street” .
During the annual Edinburgh Festival, the High Street becomes the city's central focus, and is crowded with tourists, entertainers and buskers. On the left is the High Court of Justiciary, Scotland's supreme criminal court. On the right, about one-third of the way down from the Castle toward the Palace is Parliament Square, named after the old Parliament House which housed both the law courts and the old Parliament. Parliament House is now the home of the Court of Session, Scotland's supreme civil court. St Giles Cathedral, the High Kirk of Edinburgh, also stands in Parliament Square.
