Logistical question about the dome staircase at Sacre-Coeur, looking for knowledge from previous visitors.
I have climbed a couple of spiral stairways elsewhere in Europe that ended up being a "two-way road," with people having to edge past each other going up and down. Is this the case at Sacre-Coeur?
Or is it more like I found at Notre Dame, where tourists go up one staircase and down another?
I was hoping, with this being a relatively modern basilica, that the architects may have thought to put in more than one spiral staircase to the top.
Thanks for your help.
