Horsted Keynes villagers will welcome 50 French guests from Cahagnes into their homes for a three day stay on May Day.
The two communities have been formally twinned by charter since 1971, and annual exchange visits have taken place ever since.
Paul Fairbairn, chairman of the Horsted Cahagnes Society, said: “We always enjoy hosting our French friends and we’ve a busy programme planned for them.
“With a very local theme featuring the fascinating history of the High Weald in and around Horsted Keynes, and of course the very best food and drink that Sussex has to offer.”
The group will make a steam-hauled journey on the Bluebell, the heritage railway that has its carriage and wagon works at Horsted Keynes Station.
Other highlights include a lunch from A Taste of Sussex at the Ashdown Park Hotel, with a bill of fare devised by young chef Andrew Wilson using local seasonal produce and adapting traditional Sussex recipes for a celebration meal.
A Roving Supper will see more than 100 diners tour the village to sample dishes prepared by local cooks, followed by tasting of organic cheese made in Horsted Keynes at the High Weald Dairy along with real ale and live music at the Green Man pub.
A garden party at Broadhurst Manor will give guests an opportunity to view progress of the restoration and conservation of the country house and formal gardens.
Horsted Keynes and Cahagnes share a joint history dating back to the Norman Conquest of 1066, when King William gave the High Weald parish to Guillaume de Cahaignes, a knight who’d fought with him at Hastings.
Horstede, or The Place of Horses in Saxon, became Horstede de Cahaignes and in time Horsted Keynes.
The place name is first recorded in the Domesday book of 1086.
