Richmond Hill in Richmond, London is a hill that rises gently on its northern side from the ancient Thames meadowlands around the site of Richmond Palace up to and slightly beyond the Richmond Gate entrance to Richmond Park, the former royal hunting grounds enclosed by Charles I. The descent southwestwards from this point back down to the upstream meadows is noticeably steeper, although the down gradient is less marked on its southerly and easterly progress through the park itself.
