We had an early breakfast and headed to the catacombs tour, arriving at 9 for the 10 am opening. We were not first in line, but close and, by 10, the line stretched around the corner.
Creepy and fascinating. You start out descending 100 or so steps, to dim stone-lined passages.
Eventually, you reach the ossuary area, chamber after chamber of neatly-stacked bones and skulls. Millions of them, identified by source cemetery.
First awe-struck silence, then the inevitable 'humor' burst forth.
Since we were the first party in that morning, we were mostly alone. Actually, as with yesterday's Eiffel Tower visit, it was (wait for it...)wall-to-wall people.
