The best way to see and understand the gird of La Chaux de Font is to go to the Tourist Information Centre which is located in one of the tallest building in the city. There you can take the elevator straight to the roof from where you can admire the whole landscape. Is it something unique? I do not know but the rows of four-story houses help you understand the purpose of such constructions in such environment.
As birthplace of Le Corbusier, there are some early works of this architect in the city but at the time of my visit no one was open to the public.
Le Clos is much smaller but seems to be less monotonous.
