The "Old Jail"
In the old Carthage jail which stands one block south of here, Joseph and Hyrum Smith, Prophet and Patriarch of the Mormon Church were killed by a mob on June 27, 1844. Two years later the Mormons withdrew from Illinois, where they had settled in 1839, to the Great Salt Lake.
Marker is at the intersection of Buchanan Street and Fayette Street on Buchanan Street.
