Stourhead is set to feature in a BBC series looking at various National Trust sites.
The estate will be showcased in episode three of the second series of the BBC's Hidden Treasures of the National Trust, airing on May 24.
Scheduled for 9pm on BBC Two and also available on BBC iPlayer, the programme provides insights into the conservation work going on behind the scenes at the National Trust site.
The Stourhead episode uncovers the acquisition, return, and conservation process of Angelica Kauffman’s painting, Penelope Awakened by Euriclea.
The episode follows the trail of the artwork, which was auctioned off in an heirlooms sale in 1883.
Senior collections and house manager, Emily MacCormack, said: "The 1883 heirlooms sale was a momentous moment in the history of Stourhead with many beautiful and significant paintings being sold to save the estate.
"It has been thrilling to see this painting, so loved by Henry the Magnificent, creator of the world-famous landscape garden, and sold at that sale, arrive back at Stourhead."
An archaeological dig also takes place within the episode.
The team aim to reveal the remains of the estate's original house.
A previous medieval manor had stood on the site before the current Palladian house, however no trace of the manor has been discovered until now.
Other National Trust Southwest properties that will appear in the six-part series include Saltram, Killerton, and Kingston Lacy.
The series affords audiences the opportunity to view behind the scenes while staff and volunteers work to preserve these properties.
Alistair Pegg, BBC Arts commissioning editor, said: "I’m delighted to be delving behind the scenes once more at the National Trust, uncovering hidden histories of houses and their owners, secrets of the painstaking conservation carried out on beautiful objects and buildings, and the wonderful staff and volunteers who work, often unsung, across the country."
Tarnya Cooper, director of curatorial and conservation at the National Trust, added: "History comes to life before you at National Trust properties.
"Across hundreds of sites we have well over a million objects, which tell fascinating stories of the generations of people who commissioned, made and loved them.
"Looking after such diverse objects and places takes dedicated teams of people as well as expert conservators, and we hope BBC viewers will enjoy learning more about them and their work on wonderful collections ranging from must-see paintings and furniture to books and textiles to amazing architectural features.”
