Belvoir Gardens was designed and landscaped by Elizabeth Howard, 5th Duchess of Rutland, who was married to John Manners, the 5th Duke of Rutland. It was created in 1799, the year Belvoir Castle was built. There are many unusual features to the gardens, for example the natural amphitheatre which faces the estate was formed by the moraines of glaciers and a 'root house' or summer house which survives to this day.
