Conferencegoers exit and enter the Conference Center during the 186th Annual General Conference of The Church of Jesus Christ of Latter-day Saints in Salt Lake City, Saturday, April 2, 2016.

SALT LAKE CITY — The idea for a massive meeting hall was generated from a desire by Mormon leaders to accommodate more members at general conference, as expressed by President Gordon B. Hinckley on Easter morning in April 1996.

"I regret that many who wish to meet with us in the Tabernacle this morning are unable to get in," President Hinckley said. "My heart reaches out to those who wish to get in and could not be accommodated. About a year ago, I suggested to the Brethren that perhaps the time has come when we should study the feasibility of constructing another dedicated house of worship on a much larger scale that would accommodate three or four times the number who can be seated in this building."

Twenty years later, the spacious 21,000-seat LDS Conference Center has served The Church of Jesus Christ of Latter-day Saints well. In addition to hosting general conference, the Conference Center — with the latest high-tech broadcasting equipment, water features and a rooftop garden — has become a place filled with religious artwork and a venue for stage productions, Christmas devotionals, concerts, birthday celebrations and many memorable moments.

"This is truly a magnificent building. I know of no other comparable structure built primarily as a hall of worship that is so large and that will seat so many. It is beautiful in its design, in its appointments, and in its wonderful utility. The interior is beautiful and wonderfully impressive," President Hinckley said in April 2000. "It will prove to be a great addition to this city. … We hope that those not of our faith will come here, experience the ambiance of this beautiful place, and feel grateful for its presence."

In recognition of 20 years since President Hinckley's initial Conference Center announcement, here is a timeline of highlight events that have occurred in the great Latter-day Saint hall north of Temple Square.
