Houghton Hall, Sancton, near Market Weighton, is a Grade I listed Georgian country mansion in the East Riding of Yorkshire, England, set in an estate of 5,800 acres (23 km2). Located on the estate is the village of Sancton and the vestigial remains of the ancient hamlet of Houghton. It was built c. 1765–8 by Philip Langdale (d. 1815) to the designs of Thomas Atkinson and underwent minor remodelling in 1960 by Francis Johnson. It is built in pink brick with stone dressing and slate roof, with a two-storey, 5-bay main block.
The Roman Catholic parish of Market Weighton was founded from the domestic chapel of the Langdale family at Houghton Hall. The chapel, built in 1829, was demolished in 1957. The Vale of York Polo Club was formerly located on the Houghton Hall Estate.
The Langdales lived in the area to the west of Beverley since at least the fourteenth century, when Patrick de Langdale married Elena Houghton and inherited through her estates in Houghton and Etton.
The estate at Houghton descended through the senior branch of the Langdale family from Anthony Langdale until a lack of male succession caused it to pass sideways to a cousin Peter Langdale (d. 1617) and his son Marmaduke Langdale, 1st Baron Langdale of Holme. Marmaduke was knighted by King Charles I in 1628, appointed Sheriff of Yorkshire for 1639–40 and became a devoted royalist during the Civil War, during which he fought at the Battle of Marston Moor and at Naseby. On the defeat of the royalist cause, he fled to the continent, where he contacted the future King Charles II and was made by him 1st Baron Langdale in 1658. He afterwards converted to Catholicism. The title became extinct on the death of Marmaduke Langdale, 5th Baron Langdale (d. 1778), who left no male progeny but only two daughters. The house and 1000 acres of land descended to Philip Langdale (d. 1815), the senior male member of the Langdale family, who built the present house in about 1765. The family continued as Catholic recusants, and a year after the house was built, a mission was set up there for a Catholic priest.
