For months, people work to prepare for the Christmas tradition of lights at Temple Square. Read more here about this tradition, and how the Church has made some adjustments to make this annual display more environmentally friendly. (Pictures courtesy of the LDS Newsroom.)
If you happen to be in the area during the holidays, take a look at the many free performances and events that will be held during the season.
Other temples have Christmas lights and performances as well, for example, the Mesa, Arizona temple, the Washington, D.C. temple (see pictures here). (If you know of others, please let our readers know in the comments below.) [Edited to add official link for Washington D.C. Festival of Lights here.]
Also, enjoy this video (courtesy of Mormon Soprano), showing a neighborhood storyboard nativity created by the residents who live around the Bountiful, Utah LDS temple, featuring the art of Joseph Brickey.
