The Salt Lake Temple Battlements
The battlements along the roof-line and the towers of the Salt Lake Temple give it the appearance of a castle, or a fortress. Castles were the homes of kings and lords, and were fortified to offer protection and safety to those in the kingdom.
Likewise, to Latter-day Saints the temple is a castle for the King of Kings and Lord of Lords (Revelation 17:14). The battlements symbolize God being our fortress (Psalms 18:2), and the temple being a place of refuge from the temptations and spiritual warfare of the devil and the world (John 16:33). The Salt Lake Temple, and all other temples of the LDS Church, is a sacred space where patrons can take a break from temporal matters and cares, and focus on eternal principles and their relationship with God.
The battlements also remind us of the spiritual protection offered by the priesthood and in keeping the covenants made with God in the temple.
