This photo was taken during our visit to Salt Lake City back in 2010. The Mormon/Latter Day Saints (LDS) Conference Center, located to the north of Temple Square in Salt Lake City, was completed in April of 2000. The auditorium in the Conference Center seats 21,000. The building is constructed of granite from the same quarry which provided the granite for the Temple. A semi-annual world general conference is held at the headquarters of the LDS Church at Temple Square and includes music by the famous Mormon Tabernacle Choir in the auditorium.
The builders decided that the roof should not be wasted space, and so designed a rooftop garden with pathways that meander throughout trees, native flowers, and other plantings. A guided tour of the center offers an elevator ride to the roof where you'll have a great view of the city and the mountains beyond. The pyramid shapes are actually atrium windows channeling natural light into the building below.
Conveniently, this post also fits in with Skywatch Friday - and you can see more posts here.
