Grimsthorpe Castle 

Grimsthorpe Castle is a country house in Lincolnshire, England 4 miles (6.4 km) north-west of Bourne on the A151. It lies within a 3,000 acre (12 km2) park of rolling pastures, lakes, and woodland landscaped by Capability Brown. While Grimsthorpe is not a castle in the strict sense of the word, its character is massive and martial - the towers and outlying pavilions recalling the bastions of a great fortress in classical dress. Grimsthorpe has been the home of the de Eresby family since 1516. The present occupant is Jane Heathcote-Drummond-Willoughby, 28th Baroness Willoughby de Eresby, granddaughter of Nancy Astor, who died at Grimsthorpe in 1964
