Holiness to the Lord, The House of the Lord reads the inscription over the door at every LDS Temple. The design of an LDS Temple is a monumental undertaking, and the thought, time and effort invested in each unique Temple is a reflection of the importance of the space for members of the LDS Church. The Phoenix Temple represents six years of design and construction. It is an expression of the beauty of the desert and of the light of the desert honed by iterative study of classical form and the decorative arts.
