The New Throne
Revelation 22:3-4
The new Jerusalem has no Temple. There is no need for a Temple when the object of worship is present, for the Lord God Almighty and the Lamb are the Temple.
The whole city will be the Temple "Then the Tabernacle of God shall be with men and He will dwell with them and they shall be His People and God Himself shall be with them and be their God." Revelation 21.
