The day is part of the National Festival of Archaeology, taking place across the country this month.
A joint event between the National Trust and the Lincolnshire Wolds Countryside Service, their experts will help you learn more about the fascinating history of the Lincolnshire Wolds and Gunby.
Gunby visitor experience manager, Astrid Gatenby said: “With plenty of free guided walks, activities and demonstrations, there’s lots to do for the whole family.
“There are three floors of the beautiful house and eight acres of colourful walled gardens are open to explore too.
“There will also be a sand pit for little ones to find their own archaeological treasures and historical cooking demonstrations.
“With absolutely no admission charges or additional costs for the walks or activities, there’s no better time to visit Gunby this month!
“Bring a picnic and make a day of it. Well behaved dogs on leads are welcome throughout the gardens so bring along your four-footed friends too.”
There will be a full programme of activities throughout the day, as well as free guided walks.
