Notable buildings in the Old Town include St. Giles' Cathedral, the General Assembly Hall of the Church of Scotland, the National Museum of Scotland, the Old College of the University of Edinburgh and the Scottish Parliament Building.
The area is known to have underground vaults and hidden passages that are relics of old phases of construction.
