As part of a project to seismically retrofit the Tabernacle on Temple Square, in Salt Lake City, the ornate cabinetry housing the tabernacle’s organ has been equipped with a brace that extends through the wall to a steel belt truss that now helps to tie the historic structure together.

Gathering Strength

By Brett Hansen

The uniquely domed Tabernacle on Temple Square, in Salt Lake City, has been the primary gathering place for members of the Church of Jesus Christ of Latter-day Saints for more than 140 years. Originally constructed of timber members held together with recycled iron, wooden dowels, leather strips, and friction, its domed roof structure was recently tied together and reinforced with steel trusses to protect it from the potential effects of a large earthquake in the Salt Lake Valley.
