So maybe it isn't the site of the temple after all which site would be described in that book. There is information on the internet about it.
I used to want to contribute to building a third temple but I decided it could be blasphemous because animal sacrifices would resume and that goes against Christian teachings and is an insult to Jesus' sacrifice to those who should know better.
The so-called Wailing Wall was a retaining wall, not a part of the temple itself.
