History+
The origins of Syon House date back to 1415, when Henry V founded Syon Abbey on this site. Under Henry VIII, the monastery was demolished in 1539. During the secularization, the property fell to Edward Seymour, the 1st Duke of Somerset. Between 1547 and 1552, he had Syon House built in the Italian Renaissance style on the foundations of the former monastery church. After Seymour's execution, the estate passed to John Dudley, the 1st Duke of Northumberland. His son Guildford Dudley married Lady Jane Grey, who was briefly queen in 1553 and executed the following year.
