Too many times, planners and administrators do not consider that there are people who are not as fit as they are. This happens constantly that a person who can walk easily through a tunnel, does not consider that a person, 1.9 cannot.
More and more, these tourist sites are being improved, but it still happens especially when it is a site visited mostly by local Israelis.
It shows up on our roads also. A place where the speed limit lowered to 50 KPM due to a curve, but no signs, a place that shows 4 lanes going forward, only to have one send within a minutes drive. The speed from Jerusalem to Lod changes from 70-110 in stages, non are marked.
