1. Palace of Holyroodhouse
When in Scotland, the queen and Prince Philip take residence at the Palace of Holyroodhouse in the city of Edinburgh.
The royal couple usually spends a week per year at Holyroodhouse, hosting many important events with Scottish politicians and people in attendance. When the queen arrives each year, the forecourt of the palace becomes a parade ground where she receives the keys to the city of Edinburgh.
The Palace of Holyroodhouse is also where the queen's granddaughter Zara Philips celebrated her marriage in 2011.
