This diagram -- which appears outside of the John Johnson home in Hiram, Ohio -- depicts the makeshift bowery that was built on the front of the John Johnson home where meetings, particularly Sabbath meetings, could be held.  Of this, Lorenzo Snow said: 

"I shall never forget the first time I saw Joseph Smith. It was in Father Johnson's house, In the township of Hiram, in the State of Ohio, about twenty-five miles from Kirtland. It was near Father Johnson's where the mob tarred and feathered him. When I saw him he was standing in the doorway. Before him was a small bowery occupied by about a hundred and fifty or two hundred men and women. There for the first time I heard his voice. When I heard his testimony in regard to what the Lord had revealed to him, it seemed to me that he must be an honest man. He talked and looked like an honest man. He was an honest man." (Conference Report, October 1900, p.61)

It was in this bowery that Joseph Smith spoke the day after he was tar and feathered.
