On the site where the first temple had stood, in Jerusalem. The Romans destroyed the second temple in A.D 70, but one wall, the Western or Wailing Wall, still remains and is an extremely holy site for Jews.

It happened in the year 70 CE, when the Romans destroyed the 2nd Temple.
Darius.
It was king Cyrus of Persia that released the Jews from slavery in Babylon.
The Second Temple.
They told Him this because it was true. It did take 46 years to build Solomon's temple. If you think of how they had to build everything back then, it would take seemingly forever to build anything. They had no electric/battery operated machines. And they also had to do all the heavy lifting without any help...other than more humans. And If you know the story, the temple is rather large. So it is believable that it took that long to build the temple.
King Cyrus of Persia issued the decree that the Jews may build their Second Temple (2 Chronicles 36:23). However, this decree soon saw opposition (Ezra ch.4) by the enemies of the Jews. It was set in final motion by Darius (Ezra ch.6) the king, a couple of decades after Cyrus's original permission had been granted.
it would take 7 years and a half but longer if the temple was bigger
The second Diaspora (70 CE to the present day) began when the Romans destroyed the 2nd Temple and expelled the Jews from Israel.
Read the last chapter of 2nd Chronicles and you will get your answer in full.
-- The government of Israel includes several Jews.-- There is no construction in progress on the Temple Mount.
Considering how some of the neighbors have reacted to the concept of Jews justliving in the neighborhood, can you just imagine what might happen if a truckloadof concrete and drywall pulled up on the Temple Mount one day, and Jewish workmenstarted clearing land for the Third Temple! The mind boggles. It'll be a while yet.
It took about 15 years to build a regular Maya temple.
