The Hardy Monument is a high monument erected on Dorset's Black Down hill in 1844 by public subscription in memory of Hardy. Admiral Hardy had lived in nearby Portesham, and his family owned the Portesham estate which stretched from the middle of Portesham to Black Down. The monument's site was chosen because the Hardy family wanted a monument which could be used as a landmark for shipping. The monument has been shown on navigational charts since 1846 and is visible from a distance of 100 kilometres.
