Cosmological gardens

The Enghien Gardens is a domain of 182 hectares in Enghien or ‘Edingen’, Wallonia, Belgium, created by the dukes of Arenberg in the 17th and 18th century.
The park is a green oasis full of ponds, gardens and follies.
By many, the gardens were considered a wonder of the world.
From the Arenberg castle nothing remains other than the chapel tower.
Within the park, a new château was created in the 20th century.
The Enghien municipality acquired the gardens in 1986, and opened them to the public.

The Garden of Cosmic Speculation is a 30 acre sculpture garden created by landscape architect and theorist Charles Jencks at his home, Portrack House, in Dumfriesshire, Scotland.
Like much of Jencks' work, the garden is inspired by modern cosmology.
