New Jerusalem

New Jerusalem is the city spoken of in the Holy Bible that is supposed to come down from heaven to the "new earth" that will created after the old earth passes away in the book of Revelation, a city that only the righteous can enter. The city is measured to be 1,400 miles long, 1,400 miles wide, and 1,400 miles high, with a wall that is 200 feet thick and has 12 gates made of a single pearl. The descriptions of the city itself can be found in Revelation chapters 21 and 22.
