A Look Back: The Logan Tabernacle
They began building in 1864 and completed the work in 1891 when it was dedicated by Wilford Woodruff. Its final dimensions are 65 feet by 130.
However the building was used before this dedication date. I wrote a blog post about the debate held in the basement of the tabernacle in 1889 between Joseph Smith III of the Josephite Church and Apostle Thatcher of the Utah Church.

This building is a monument to pioneer character. Even more remarkable is that the Logan Temple was built at the same time, with even greater sacrifice. However the buildings had different purposes.
