It has been in the hands of the Stonor family for 850 years. As Catholics, they suffered under Henry VIII and there is a priest hole to visit, where Edmund Campion hid. In the grounds is a huge stone circle, which gives the estate its name, and a more modern addition - an adventure playground, called Wild Woods, with sand and water for younger children and adventurous climbing areas to suit up to age 15 or so. The visitor's centre has toilets, with baby changing, and food. The house is not wheelchair friendly, as even the ground floor is not all on one level.
