This palace is the royal family's official residence in Scotland but is more famous as the 16th-century home of the ill-fated Mary, Queen of Scots. The highlight of the tour is Mary's Bedchamber, home to the unfortunate queen from 1561 to 1567. It was here that her jealous second husband, Lord Darnley, restrained the pregnant queen while his henchmen murdered her secretary – and favourite – David Rizzio. A plaque in the neighbouring room marks the spot where Rizzio bled to death.

　　The palace developed from a guesthouse attached to Holyrood Abbey that was extended by James IV in 1501. The oldest surviving part of the building, the northwestern tower, was built in 1529 as a royal apartment for James V and his wife, Mary of Guise. Mary, Queen of Scots, spent six turbulent years here, during which time she debated with John Knox, married both her second and third husbands, and witnessed Rizzio's murder.

　　The self-guided audio tour leads you through a series of impressive royal apartments, culminating in the Great Gallery. The gallery's 89 portraits of Scottish kings were commissioned by Charles II and supposedly record his unbroken lineage from Scota, the Egyptian pharaoh's daughter who discovered the infant Moses in a reed basket on the banks of the Nile. The tour continues to the oldest part of the palace, which contains Mary's Bedchamber, connected by a secret stairway to her husband's bedroom, and ends with the ruins of Holyrood Abbey.
