Great art, magnificent ! [=D>]
It reminds me of a park near the Chateau de Versailles that I visited 20 years ago.
It's called 'France miniatures' at Elancourt here is the link of the site: Click here
It's exactly the same idea as your concept: the most beautiful monuments are reproduced in the same place !
Do you recognize the shape of the park ?
