The Garden of Cosmic Speculation

The Garden of Cosmic Speculation is at Portrack House, near Dumfries in South West Scotland. It is a private garden created by Charles Jencks.

The garden is inspired by science and mathematics, with sculptures and landscaping on these themes, such as Black Holes and Fractals. […]

The garden is private, however it is often open on one day each year through Scotland’s Gardens Scheme and raises money for the Maggie’s Centres, a cancer care charity named for Maggie Keswick Jencks, the late wife of Charles Jencks.
