Conspiracies, plots and other dramatic turns in Scottish history were the scenes played out at the Palace of Holyroodhouse. Established as the monarchical residence for the kings and queens of Scots more than six centuries ago, it is now the Queen's formal residence in Scotland. Built on the ruins of a medieval abbey, this elegant, quadrangular complex was built in the 16th Century with added extensions in the following century. Intriguing stories abound in its state apartments that give a glimpse into the life of its famous residents like Mary, Queen of Scots, Bonnie Prince Charlie and George IV. The Great Gallery displays fascinating exhibitions from the Royal Collection, while the expansive, beautiful gardens add further charm to this regal castle.
