You are standing at the entrance to Edinburgh Castle, the most besieged place in Great Britain. This fortress has witnessed over 20 separate sieges throughout history, changing hands between the Scots and the English many times during the Wars of Independence. Inside these walls lie the Honours of Scotland, the oldest crown jewels in Britain, which survived being hidden from Oliver Cromwell’s army in the seventeenth century. For centuries, the castle also housed the Stone of Destiny, a sacred block used for the coronation of monarchs, which was finally returned to Scotland in 1996 after 700 years in London, although it has recently moved to a new permanent home in Perth Museum. A practical tip for your visit: if you are near the Mills Mount Battery at exactly 1 p.m., keep your ears peeled. The One O'Clock Gun is fired daily, except on Sundays, Good Friday, and Christmas Day. This tradition began in 1861 as a time signal for ships in the Firth of Forth. Just remember, if you plan to go inside the castle, suitcases and large backpacks over 30 liters are not permitted for security reasons.
