Edinburgh Castle is Scotland’s most famous fortress, perched dramatically on an extinct volcanic crag above the city. A ticketed visit reveals centuries of history, from the tiny 12th-century St Margaret’s Chapel and the Scottish Crown Jewels to the Stone of Destiny, the Great Hall and the One O’Clock Gun. Sweeping views over Edinburgh reward the climb, and the castle’s museums bring its royal and military past to life. Commanding and unmissable, it is the city’s defining landmark and the highlight of any visit.
