Arlington Court is a neoclassical style country house built 1820–23, situated in the parish of Arlington, next to the parish church of St James, 5+1⁄4 miles NE of Barnstaple, north Devon, England. It is a Grade II* listed building. The park and gardens are Grade II* registered on the National Register of Historic Parks and Gardens.The house was commissioned by Colonel John Palmer Chichester (1769-1823) to the design of the North Devon architect Thomas Lee, replacing the earlier Georgian house of about 1790, built on a different site and demolished, designed by John Meadows. Arlington Court was considerably expanded in 1865 by John Palmer Chichester's grandson, Sir Alexander Palmer Bruce Chichester, 2nd Baronet (1842-1881), son of Sir John Palmer Bruce Chichester, 1st Baronet (d.1851). In 1873 according to the Return of Owners of Land, 1873 the Arlington estate comprised about 5,300 acres.Sir Bruce's unmarried daughter and heiress, Rosalie Chichester (d. 1949), donated the mansion to the National Trust together with 3,500 acres (14 km2) two years before her death in 1949.
Today, the house, together with the Chichester family's collection of antique furniture and an eclectic collection of family memorabilia, is fully open to the public.
