Richmond Hill

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 deer park 'emparked' or 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. Richmond Hill is also the name of the road that runs from Richmond town centre to the top of the hill, and is one-way up the hill along its northern part.

Richmond Hill, as a name, is an unintentional pleonasm where “-mond” and hill means practically the same thing. The origin as a description of a place in France has lost its use as a description to become a general place name. It just so happens that another hill ended up adopting its name.
