Marble Hill House

Marble Hill House is a Palladian villa on the River Thames in southwest London, situated halfway between Richmond and Twickenham. The architect was Roger Morris, who collaborated with Henry Herbert, Earl of Pembroke, one of the "architect earls", in adapting a more expansive design by Colen Campbell.

Orleans House is close by and Ham House is across the river, accessible by Hammerton's Ferry.
