If the date “1752” found etched in a cornerstone is correct, then this is the oldest building in the English colonies west of the Alleghenies. That date would make it older than the Fort Pitt Blockhouse by twelve years. Father Pitt tends to doubt the authenticity of the date; but there is no doubt that this is a very old building, almost certainly from the 1700s, and one that ought to be preserved at all costs.
Update: The building is now generally regarded as dating from 1782, which is still very old for a stone building in Pittsburgh. Pittsburgh’s Old Stone Tavern Friends Trust is trying to get enough money together to preserve this building. If you have extra money sitting around and were wondering what to do with it, here is a suggestion.
