City Council yesterday voted unanimously to approve city historic status for the Old Stone Tavern at 434 Greentree Road, West End.
The building's age has not been established, although 1756 is etched on a cornerstone.
Michael Shealey, an amateur historian who researched the building's past, said that Daniel Elliott, for whom the Elliott neighborhood was named, owned the land that early but probably built the tavern sometime later than 1756.
The Carnegie Library has a register of accounts from the 1790s that corresponds with business conducted in the current building.
It is one of few 18th century buildings known to remain in the city. The others include the Schenley log house in Schenley Park, the Fort Pitt Block House in Point State Park and the John Woods House in Hazelwood.
Daniel Elliott was an Indian trader who built the Old Stone Tavern, which he operated in addition to a nearby sawmill and a ferry across the Ohio River. The building was a tavern until it closed several years ago. It is owned by Lee Harris of Harris Masonry, the business next door.
