Hmmmm. Interesting spot for a crypt and sealed up like that.
I have two kids going to school in Philly at the same time (Yes, money's an issue), and drive past Fairmount pretty often over the course of the year. I may have to make a side-trip or two when they go back in the fall instead of whizzing past.
Yeah they're cool looking I wish I had found one of them. And that wasn't a crypt lol. would be pretty creepy if it was in the middle of a hiking trail. There was a history plaque next to it that said it used to be a natural spring and spot to get drinking water. water filtered naturally down through the rocks and collected there. Was built in the 1800's and sealed up in the early 1950's because the water became too polluted to drink....figures
