The Garden of Cosmic Speculation is a 30 acre (12 hectare) sculpture garden created by landscape architect and theorist Charles Jencks and his wife, Maggie Keswick Jencks, on Maggie's land and their home together, Portrack House, in Dumfriesshire, Scotland. Like much of Jencks' work, the garden is inspired by modern cosmology.
