Palmyra, Wayne County, New York is sacred ground, where Joseph Smith received the First Vision of the Heavenly Father and Christ in 1820. At that time, Joseph was just 14 years of age. How the great revelations are made to the faithful and the pure of heart!
There is a beautiful Church of Latter-Day Saints in Missouri, as there are in Calgary, Caracas, and all over the world, with a church also announced in Lisbon, Portugal.
But the grounds where the city is planned, what I termed New Jerusalem, is in Missouri,
used as farmland or maybe disused farmland. That I hope they will use for the Temple for Christ, for His Second Coming.
The Valley of God, or Adam-ondi-Ahman (which means Peace in some languages) is also sacred, where Adam shall meet with angels prior to the Second Coming. May we all be blessed with that in this generation, I pray to God.
