The Queen will take part in an ancient ceremony in Edinburgh as she continues to mark her Diamond Jubilee with a week-long visit to Scotland.
The annual Ceremony of the Keys will see the monarch handed the keys of the city and welcomed to "your ancient and hereditary kingdom of Scotland" by the Lord Provost.
Monday's ceremony is part of a number of events due to take place as the country celebrates the monarch's 60-year reign.
After the ancient ritual, the Queen and the Duke of Edinburgh will visit the Scottish National Portrait Gallery.
Later in the week the Queen and the Duke plan to attend a jubilee thanksgiving service at Glasgow Cathedral and will visit George Square, Clydebank and Greenock.
Meanwhile on Friday Her Majesty will travel to Perth, awarded city status to mark the jubilee. The Queen will be given the keys to the city and the Duke will receive the freedom of the city.
Later they visit RHQ Black Watch Museum in Balhousie Castle; Perth College; University of the Highlands and Islands; and Scone Palace for lunch.
