From an 1884 fire-insurance map of part of downtown Pittsburgh:

The long-gone First United Presbyterian Church (not First Presbyterian—that’s a different church, still going; these were the United Presbyterians) on Seventh Avenue. Note:

1. “Meat storage” in the basement of the church.

2. “Passage under gr’d” to the J. Stevenson & Co. ham house.

Fortunately, some Presbyterians repented of their evil ways and left the First United Presbyterian Ham House, as we can see by the fact that there was a church for reformed Presbyterians just behind First United Presbyterian.
