The London home of the Duke of Northumberland, whose family were granted the former monastic site at the end of the 16th-century.
The Tudor mansion was remodelled by Robert Adam for the 1st Duke in 1760’s and the interiors are an architectural tour de force – the great hall may be Adam’s finest classical work.
Syon has 30-acre gardens within a 200-acre park transformed by ‘Capability’ Brown and a stunning domed conservatory designed by Charles Fowler in the 1820s.
