Dinton Castle

Dinton Castle stands in Dinton, Aylesbury, United Kingdom; it was erected in 1769 by the English landowner Sir John Vanhattern.

Local tradition holds that before the castle existed the seventeenth‑century hermit John Bigg lived in a cave on the property. In 1769 Sir John Vanhattern built the octagonal folly as an eyecatcher for the Dinton Hall estate, and he finished its limestone walls so they displayed his fossil collection, with ammonites set into the masonry.

During the nineteenth century the structure saw practical use linked to the estate, serving at times as accommodation for servants and as an improvised meeting place for a local non‑conformist congregation. When used for gatherings a canvas roof was reported as a temporary cover. Over many decades the tower fell into serious disrepair and for a long period the ruin was supported by scaffolding.

Official protection and concern for the ruin grew in the twentieth century. It was placed under statutory listing in 1951, described then as ruinous, and it later appeared on heritage risk registers, being recorded as a Priority A entry on the Heritage at Risk Register and included on English Heritage and the local council’s Buildings at Risk lists. The fabric was stabilised in 2009, with new lintels and repairs to windows and the entrance arch. The property changed hands in 2012, one record naming Brett O’Consnor as purchaser, and in 2016 Jaime (also reported as Jimmy) Fernandez and his wife Mimi bought the site. Aylesbury Vale District Council granted planning permission on 26 January 2017 to convert the ruin into a two‑bedroom residence. Repair and conversion work took place between 2017 and 2018; the restoration attracted national and international media attention and was followed by occupation as a family home. Reports indicate the renovation cost exceeded £300,000 in addition to an earlier purchase price of about £100,000. The restored property was sold in 2021 and became available through a short‑term rental listing in June 2022.
