“According to Keith Stepan (former Managing Director of Temple Construction), many LDS temples are thematic, making use of a single visual motif to unify the exterior architecture and interior design and furnishings. These unifying motifs potentially point to a particular doctrine or concept. At the Mt. Timpanogos Utah Temple, for example, we see an arching motif in the main east and west windows pointing to the theme of Jacob’s Ladder. At the San Diego Temple, 2 interlocking squares are used over 10,000 times throughout the structure, potentially symbolizing the Melchizedek Priesthood. In these and other LDS temples it is the fence design that first reveals their general visual theme.” – Val Brinkerhoff, The Day Star – Reading Sacred Architecture (Book 2), 131
In a recently published book “Sacred Walls: Learning from Temple Symbols” by Gerald E. Hansen and Val Brinkerhoff (photographer), readers are presented with a series of doctrinal themes that are explained using the particular architectural symbolism of various temples.
On the inside cover flap of the book, “Sacred Walls: Learning from Temple Symbols” it states:
Both books and buildings have voices. But rather than the letters of an alphabet, buildings use towers and spires, columns and buttresses, mosaics and paintings, glass and geometric figures, and statues and friezes to speak volumes. However, even though architectural symbolism existed before the written word, the message of a building is often difficult for most of us to recognize.
For Latter-day Saints, temples are the most important and symbolic buildings in existence. Through temples the unique doctrines of the restored gospel are communicated. Although the bulk of this instruction occurs inside the temples, temple exteriors also tell of these profound doctrines — when you understand how to read them.
