The "Groeneveld Castle " in Baarn. In the seventeenth and eighteenth centuries it was cutomary for wealthy Amsterdam people tp purchase an outdoor area where they could relax during the summer.
These outdoor areas often lie on the border of sandy and pat soil.
I visited it 2013 so these photos are from the archives
There is a great garden.
With funny sculptures. It is closed now as almost all public areas now but at least we have the pictures to dream away...
