Syon House
London’s great time-capsule: a Tudor-era power site wrapped in Robert Adam’s most theatrical interiors and set within sweeping parkland. Inside, Adam turns rooms into stage sets—stone-cold Roman grandeur dissolving into candy-bright neoclassicism—while the Percy family collection threads van Dyck, Lely and Italian masters through the route. Outside, the riverside landscape frames one of Britain’s earliest monumental glasshouses, the Great Conservatory, a glamorous prelude to the Victorian age of iron and glass. Plan 90–120 unrushed minutes: house first (guided tours are excellent), then gardens and conservatory.
