This society tomb's marble is long gone, but I'd guess the recent brick- loss was from Gustav, since the inside is in really excellent shape and likely hasn't been exposed very long.

You can see the roof beams are still in place, and the bricks quite solid, but the amazing thing is that sheet of slate that served as a shelf for the coffin. This particular tomb held four coffins at a time, each (even the bottom) on one of those shelves, with an open area below. Of the many open tombs you see around the city, this is the first with a liner still inside that I've seen. The fact that it's up high will help it last a little longer, and maybe (tho not likely) they'll patch it up before it starts to crumble. It's also lost half of the bottom tomb, thanks to our super soft soil and high water table.
