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 not abundant with plants, but sets mathematical formulae and scientific phenomenae in a setting which elegantly combines natural features and artificial symmetry and curves. It is probably unique among gardens, and contrasts nicely with the historical and philosophical themes of the less spectacular but equally thoughtful Little Sparta. Little Sparta is a garden at Dunsyre in the Pentland Hills near Edinburgh, created by artist and poet Ian Hamilton Finlay and his wife Sue Finlay. This Dumfries garden, known as The Garden of Cosmic Speculation, is not your everyday example of landscaping; instead it is based on mathematics and science mixed with nature and man-made lakes. Built in 1989, it has been called by some the most important garden in the 21st century.
