High up on what is believed to be an extinct volcano, Edinburgh Castle has dominated the city for almost 1,000 years. The landmark is visible from almost anywhere in Edinburgh.
Edinburgh Castle has had many uses over the years. In the 18th and 19th centuries, Edinburgh Castle was a prison for sailors. Some incarcerated in the dungeons of Edinburgh Castle, who left graffitti on their prison walls, sailed with John Paul Jones, founder of the US Navy.
More than a million people a year visit Edinburgh Castle, thousands to attend the Edinburgh Military Tattoo, a colorful pageant of the Scottish regiments, complete with bagpipes, tartans and lots of horses, held every August.
