The Crown Jewels of Scotland are a collection of royal regalia that symbolize the monarchy of Scotland. They include the Crown, Sceptre, and Sword of State, which were used in the coronation of Scottish kings and queens. These artifacts are housed in the Crown Room at Edinburgh Castle and are among the oldest regalia in Europe. The Crown Jewels date back to the 15th century, with the oldest piece being the Sword of State, created in 1507. They were hidden for over a century after the Union of the Crowns in 1603 but were rediscovered in 1818. Today, they are a significant part of Scotland's heritage and attract many visitors.
