More than 90,000 people are expected to attend Chatsworth Country Fair over the next three days. Special guests at the event will include 'The Great British Bake Off' judge, Mary Berry, and the show's President, Lord Sebastian Coe.
The event will feature pipe and military bands, parades, hot air balloons, parachuting and a demonstration of local produce.
Lord Sebastian Coe will be in Leicestershire to inspire the next generation of athletes today.
It's as part of the Olympics and Paralympics Roadshow which aims to get more young people interested in sport.
He'll be visiting the Beauchamp College in Oadby.
Burghley House has received a gift from Lord Sebastian Coe.
He has given his London 2012 Olympic torch to the historic home.
Lord Burghley, who lived between 1905 and 1981, was an Olympic medal-winning hurdler. He also helped to deliver the 1948 London Games.
An original Olympic torch from the 1948 games is already on display at the Elizabethan home and will now be joined by the 2012 version.
The 2012 torch has been to the house previously as it was part of the relay, earlier this year.
