(1200 kilometers on a side)
And there came unto me one of the seven angels which had the seven vials full of the seven last plagues, and talked with me, saying, Come hither, I will shew thee the bride, the Lamb's wife.
And he carried me away in the spirit to a great and high mountain, and shewed me that great city ... And the city lieth foursquare, and the length is as large as the breadth: and he measured the city with the reed, twelve thousand furlongs. The length and the breadth and the height of it are equal. Revelation 21:9-16
