The Garden of Cosmic Speculation was created by Charles Jencks and Maggie Keswick in Dumfries, Scotland in 1989. It contains unusual geometric patterns in order to inspire the mind. The mound pictured above was designed around the Fibonacci sequence. This is a private garden and open to the public only one day a year.
