Syon House, and its 200-acre (80 hectare) park, Syon Park, is in west London, historically within the parish of Isleworth, in the county of Middlesex. It belongs to the Duke of Northumberland and is now his family's London residence. The family's traditional central London residence had been Northumberland House, now demolished. The eclectic interior of Syon House was designed by the architect Robert Adam in the 1760s.

Syon House derives its name from Syon Abbey, a medieval monastery of the Bridgettine Order, founded in 1415 on a nearby site by King Henry V. The Abbey moved to the site now occupied by Syon House in 1431. It was one of the wealthiest nunneries in the country and a local legend recalls that the monks of Sheen had a Ley tunnel running to the nunnery at Syon. In 1539, the abbey was closed by royal agents during the Dissolution of the Monasteries and the monastic community was expelled.

In 1541 and part of the following year, Henry VIII's fifth wife, Catherine Howard, was brought to Syon for her long imprisonment. In February 1542, she was taken to the Tower of London and executed on charges of adultery. Five years later when King Henry VIII died, his coffin was brought to Syon on its way to be buried in Windsor.

After the closure of the abbey, Syon became the property of the Crown for a short time before coming into the possession of the 1st Duke of Somerset. He then had Syon built in the Italian Renaissance style before his death in 1552. In 1557 it was proposed to return it to its original purpose as an abbey, but this idea was short lived. Syon was acquired in 1594 by Henry Percy, 9th Earl of Northumberland (1564-1632), and has remained in his family ever since.
