Caythorpe Court is a Grade II* listed former hunting lodge situated about one mile to the east of Caythorpe, Lincolnshire, England. It was originally built in 1901 for Edgar Lubbock, a brewer and banker, to the designs of Sir Reginald Blomfield. In 1946 it became the Kesteven Agricultural College, which was renamed the Lincolnshire College of Agriculture and Horticulture from September 1980. The college became the De Montfort School of Agriculture, but the site was closed in 2002. After being sold to property developers, who proposed to use it to house asylum seekers, it was acquired by PGL who now operate it as a centre for adventure based holidays for adults and children.
