Heritage Open Day: Two guided heritage walks around the ornamental gardens of Thornton Park and exhibition of photos to coincide with the annual Picnic in the Park where there will be live music, activities for children, tea and cake. Thornton Park is a beautiful open green space much loved by the people of Kingsthorpe but it was not always open to the public as it was a private home and country estate from 1773 when the historic house we see today was built. It wasn’t until 1939, two years after the Northampton Corporation purchased the estate and hall that it was opened officially as Kingsthorpe Park. The historic house is now privately owned and divided into flats so we cannot access the building during our heritage walks.
