There are twelve (12) gates hanging from the wall of the New City of Jerusalem. These 12 gates are oriented in groups of three and face the four cardinal directions of the compass needle: the north, south, east and west. There is an angel at each gate, residing in a gatehouse. The 12 gates are each made of a 'single' pearl, giving these the name "pearly gates". The names of the twelve tribes of Israel are written on the 12 gates.
