Dinton Castle (also known as Dinton Folly) is located just north of the village of Dinton, in Buckinghamshire and was built as an eyecatcher from Dinton Hall by Sir John Vanhatten in 1769. He used the castle to store his collection of fossils in the limestone walls. According to Rev. Callander (formerly of Dinton), the 'castle' was at one time used as a temporary meeting place for a local non-conformist congregation. To improve its habitability a tarpaulin had been used as a makeshift roof.
The castle has been neglected for many years and was, for a long time, supported by scaffolding. Although there is a public footpath, the castle and the land is privately owned
