Built in the 12^th century, sacked by Edward I in 1296, the castle was recaptured in 1313 and rebuilding was started in 1368. Every occupant modified or added to the original structure, so that today it is a rich architectural mixture of palace, fortress, barracks, chapel and war memorial. Edinburgh castle is also the home of the Scottish Crown Jewels, the oldest Royal Regalia in Britain. With many sights to see, from the giant siege gun Mons Meg to the room where Mary, Queen of Scots gave birth to James VI and I, the first ruler of both Scotland and England. In short: A must!
