The Old Salt Lake Tabernacle was built in 1852. It was home to the now world-famous Mormon Tabernacle Choir from 1873 until the Adobe Tabernacle was torn down in 1877 to make way for Assembly Hall. The replacement Salt Lake Tabernacle is a marvel of design and engineering. The 150 by 250 foot domed roof was constructed with a lattice truss of timbers held together with wooden pegs and rawhide. Most believed the canvas roof would collapse during its inaugural year in 1867. The LDS General Conference was held within the auditorium until 2000. The Tabernacle Choir at Temple Square still performs incredible concerts in the facility.
