Dinton Castle, which is also known as Dinton Folly, is located just north of the village of Dinton in Buckinghamshire and was built by Sir John Vanhatten in 1769 as an eyecatcher from Dinton Hall. He used the Folly to store his collection of fossils in the limestone walls.

It has recently been restored into a two bedroom home giving it a new lease of life and ensuring its long-term survival as a well-loved local landmark and unique Heritage Asset.

The story of its restoration has been documented on the new series of Grand Designs 2018
