In Mormonism, leaders of the Church of Jesus Christ of Latter-day Saints create temples in places all around the world. Temples allow members to seal families together, perform baptisms for the dead, make covenants, and do work for others. The temple and the temple grounds are a place of silence, and peace.
The first temple made by the Latter-day Saints was the Kirkland Temple, now owned by the Community of Christ, a church founded by members of the LDS Church who did not leave with Brigham Young to Salt Lake. The Kirkland has been undamaged and the foundation is the same as the time it was built. Unlike the LDS Church and how they respect temples as a house of God, the Community of Christ first used the Kirkland Temple as a barn, holding all kinds of farm animals in the building. Later, they used it as a tourist attraction, and hold tours. The LDS Church does NOT allow non-members to enter the temple unless they are a member and have a temple recommend.
There are about 140 constructed temples have been built around the world since. Around 14 more are under construction and another 14 have been planned.
