Wallington is a country house and gardens located about west of Morpeth, Northumberland, England, near the village of Cambo. It has been owned by the National Trust since 1942, after it was donated complete with the estate and farms by Sir Charles Philips Trevelyan, the first donation of its kind. It is a Grade I listed building.HistoryThe estate was owned by the Fenwick family from 1475 until their financial problems caused them to sell their properties to the Blacketts. The hall house was rebuilt in 1688 around the ancient pele tower house for Sir William Blackett and was later substantially rebuilt again, in Palladian style, for Sir Walter Blackett by architect Daniel Garret, before passing to the Trevelyan family in 1777. Charles Philips Trevelyan inherited the property from his father George Otto Trevelyan in 1928.
