The Inventory of Gardens and Designed Landscapes in Scotland is a listing of gardens and designed landscapes of national artistic and/or historical significance, in Scotland. The Inventory was originally compiled in 1987, although it is a continually evolving list. From 1991 it was maintained by Historic Scotland and Scottish Natural Heritage, and is now updated by a dedicated team within Historic Environment Scotland. As of 2016 the Inventory includes over 300 sites across Scotland.
