The Queen was last at the Royal Highland Show 25 years ago
The Queen and the Princess Royal have arrived at the Royal Highland Show to help celebrate the agricultural showcase's 225th anniversary.
The four-day event, held on the outskirts of Edinburgh each year, attracts thousands of visitors from around the country.
Showjumping, music performances and shopping take place alongside livestock competitions at the Ingliston event.
The Queen and Princess Anne have been enjoying a tour of the Ingliston site.
The Princess Royal is a frequent visitor to the show but the last time the Queen attended was in 1984.
Princess Alexandra of Kent is also due to attend the show, which runs until Sunday.
Ray Jones, chief executive of the Royal Highland and Agricultural Society of Scotland, said: "We are delighted to welcome the Queen as our patron in our 225th year.
Thousands of visitors are expected to visit the show over the weekend
"The Royal Family have been strong supporters of the society and its activities over the years and we look forward to pointing out some of the show's highlights."
First Minister Alex Salmond was also at the event on Friday to host a tea party for veterans of the Women's Land Army who played a vital role during World War II.
The First Minister also emphasised the importance of farming to the economy.
He said: "Our farming and other rural industries contribute greatly to our national economic fortune and to communities the length and breadth of Scotland.
"They are a fundamental part of the national economy and society, which is why the Scottish Government is doing all we can to ensure the sector has a sustainable, profitable future."
The Queen's father, King George VI, bestowed the title "Royal" on the show at the Inverness event in 1948, in the days when the show moved around Scotland each year. It settled at its current home in 1960.
The Queen arrived at the event at about 1100 BST on Friday, where she was shown livestock before presenting trophies to people competing in the horse events.
She is to have lunch at the site at about 1300 BST and is due to leave at 1430 BST.
