Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God. II Thessalonians 2:3-4
The Temple will be rebuilt in Jerusalem, as indicated by the Scriptures cited above. I don't recognize the Vilna Gaon as authoritative, but I find the following item interesting, or as Joel Rosenberg likes to say, "curious":
If the 18th-century rabbinic authority the Vilna Gaon was right, on March 16, 2010, construction will begin on the third Temple. His projection states that the auspicious day will coincide with the third completion of the Hurva Synagogue in Jerusalem's Jewish Quarter.
The great day is at hand: On March 15, the reconstructed Hurva Synagogue, considered the most important house of prayer in Jerusalem will be rededicated. It was last destroyed in the War of Independence.
A good book on the rebuilding of the Temple is Ready to Rebuild (1992) by Thomas Ice and Randall Price. There's also a companion video produced by James DeYoung.
