Looks like since 2005 there has been a law in France: Law of 11 February 2005
This law specifies that accessibility for disabled people, regardless of their category of disability (physical, visual, hearing or mental), to establishments receiving the public or places open to the public will become mandatory on 1 January 2015.
Is that stairway a "public place"?
In John's example does that mean in the States or elsewhere the laws can be skirted if the access if too difficult to meet ADA standards?
Here they also built a permanent stage on the dock by the Wall House Museum, with stairs for access on the front and the back, where they could have easily been a ramp on one side or the other. Imagine a child or adult in a wheelchair who wins an award for something but cannot access the stage for the award ceremony due to lack of access. You'd think public projects would take these things into consideration.
Back to the staircase, lovely views from up there. They had to take out the original version put in a few months ago, as they didn't put in any landings, it was a strait up set of stairs - and the law requires the landing every certain number of steps, so that is one very expensive project.
