Salt Lake Tabernacle

On Temple Square in downtown Salt Lake City, this domed hall built between 1864 and 1867 is famed for its acoustics and its enormous pipe organ, one of the largest in the world. The elongated turtle-shell roof spans the interior without internal columns, an engineering feat achieved with wooden lattice trusses pegged and lashed together. For generations it hosted the broadcasts of the Tabernacle Choir. Guides often demonstrate the acoustics by dropping a pin at the pulpit, audible from the far end of the hall.
