HISTORIC DEVELOPMENT

When Richard Arundel, Surveyor General to the King's Works, inherited the Allerton estate in 1720, he built a new house and enlarged the park. Viscount Galway, the last of the Mauleverer/Arundel line, inherited in 1772 and then, in 1786, the estate was bought by Prince Frederick, Duke of York. After three years he sold it on to Colonel Thornton who changed its name to Thornville Royal.

Charles Philip, sixteenth Lord Stourton, purchased the estate in 1805 and was responsible for further alterations to the main house, and the building of the chapel. A massive remodelling of the house was subsequently carried out by George Martin for Charles, nineteenth Baron of Stourton to whom the property passed in 1846. The work, started in 1848 and largely completed by 1851, encased the Georgian mansion in a neo-Jacobean shell, and in so doing, doubled its size. During the First World War the house was used as a hospital and, following the death of Lord Stourton in 1965, it was again used for a variety of institutional purposes. It returned to private use in 1982.
