Lumley Chapel, the oldest building in Cheam, can be found in St Dunstan's churchyard and is the only surviving remnant of a 900-year-old building that once stood on this site. John Lumley, a Catholic aristocrat and art collector, refurbished the building as a burial place for himself and his two wives in the late sixteenth century.

Opulent stone monuments fill the walls and a huge tomb near the door shows Lumley's first wife Jane Fitzalan, carved in alabaster, wearing a starched ruff and headdress, her gown flowing as she kneels in prayer.
