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
