Presenter Fiona Bruce pictured and the team of Antiques Roadshow experts will be at the picturesque venue near Silsoe on July 19.
Producer Robert Murphy said: “We are looking forward to welcoming thousands of visitors when we bring Antiques Roadshow to Wrest Park.
“It promises to be an entertaining day out at the start of the holidays and we are looking forward to seeing cherished objects and hearing personal stories.
“It is a great free, family day out and you can see how we make one of BBC One’s most popular programmes.”
Wrest Park is a spectacular country house, designed to look like a grand French chateau. It is grade I listed, as are its landscaped gardens – one of the most complete 18th century landscaped gardens in the country.
It has a remarkable history, including as a military hospital and convalescent home during the First World War.
Doors open for Antiques Roadshow visitors at 9.30am and close at 4.30pm. Entry to the show is free and no tickets or pre-registration is required.
