Some info on Holyrood:
The Palace of Holyroodhouse is the official (government-owned) residence of the Monarch of the United Kingdom in Scotland. Founded as a monastery by David I, King of Scots in 1128, it has served as the principal residence of the Kings and Queens of Scots since the 15th century. The Palace stands at the bottom of the Royal Mile in Edinburgh, the opposite end to Edinburgh Castle. Queen Elizabeth II spends one week in residence at Holyrood at the beginning of each summer, to host garden parties and official ceremonies (would be nice to be invited to one of these!). She then continues to Balmoral Castle (which she owns) for her annual two-month summer holiday.
Here is a photo of it taken from Calton Hill circa 1878
