BBC’s Antiques Roadshow will be filming for its 37th series in the grounds of Chenies Manor on Thursday, July 3.
The doors open at 9.30 am and close at 4.30pm. Entry to the show is free.
Presenter Fiona Bruce said: "This will be my 7th year on the Antiques Roadshow and I still feel so lucky to be presenting the programme.
"Every week is different; a new location and thousands of new visitors. The only constant is the pleasure of the unexpected - we never know what will turn up, from the most fabulous Faberge to the most humble object with a riveting story."
Some of Britain’s leading antiques and fine arts specialists will be on hand to offer free advice and valuations to visitors, who are invited to raid their attics and bring along their family heirlooms, household treasures and car boot bargains for inspection by the experts.
During the last series the Roadshow unearthed some amazing finds - memorabilia bought from the last survivor of the Titanic, a teapot once owned by Nelson and a portrait by Van Dyck which turned out to be worth more than £300,000.
People with large pieces of furniture or other big items can send details and photographs of their objects to: Antiques Roadshow, BBC, Whiteladies Road, Bristol BS8 2LR or e-mail them to: firstname.lastname@example.org. It may be possible to arrange to look at the item in advance and organise transportation to the venue.
