I am looking for gardens or parks in a temperate climate that have been developed on a sloping site, whether a natural hillside or man-made. The idea is to examine and compare gardens (both public and private) on precipitous slopes as a design challenge. Often this ground got and still gets terraced - but other means of coping with the slope have been developed. It is of great interest to this study to first of all find existing examples of gardens where the slope was turned from a nuisance into an advantage i.e. made an essential part of the design.
TIA
