Just for comparison's sake

This is a hallway in the Hanoi Hilton, built by the French in the late 1800's, when Vietnam was part of French Indochina. This is where my dad spent 7 1/2 years of his life. Actually, worse than that, he spent four of those years totally isolated in a cell away from this main building. The Conciergerie doesn't have anything on this desolate place.
