A modest two-storey, five-bay country house originally named Warter Hall was built by the Pennington family of
Muncaster Castle in the late 17th century. It was renamed Warter Priory in the 1830s after the former Augustinian priory in nearby Warter village. Major extensions were made in 1872, and it was re-fronted with corner towers added. The last
Lord Muncaster sold the house in 1878 to Hull shipping magnate
Charles Wilson (later Lord Nunburnholme). In 1885 impressive alterations were made, including adding a great baronial-style hall and a tall entrance tower. The house now had nearly 100 rooms. Lord Nunburnholme died in 1907, survived by his widow for another 20 years. After Vestey's death, the house and the then estate were sold in December 1968 for £4 million to
Oswald Phipps, 4th Marquess of Normanby and the
Guinness Trust, primarily for shooting. The house contents were auctioned in March 1969, and when a tenant could not be found the house was considered surplus to requirements, as was
common for country houses at that time. The house was demolished and the gardens bulldozed in 1972, the rubble being used to fill the garden lake. In 1998
The Times reported that the house had been described as "one of Yorkshire's greatest country houses, an architectural gem" and a "French-style grand house" with a marble-staircase and a elaborately carved oak fireplace. It noted it could also have been viewed as a "Victorian monstrosity" with 100 rooms and more than 365 windows requiring 40 servants and a "bottomless pocket" to maintain. ==Medieval Augustinian priory==
