Can someone explain this to me??

Someone who’s been to Israel here. 

Israel requires foreign leaders to do two things their first time visiting: Visit the Yad Vashem Holocaust museum, and visit the Western Wall. The idea is so they can better understand what the Jewish people have suffered, and the heart of the Jewish people now. 

The Western Wall is a super strict and secure location.  To go to the wall itself, you must wear a head covering, often a Kippah or a Shtreimel. Some people place their head on the wall, or even kiss it, although not required. Some Orthodox Jews spend hours a day at the wall reading Torah.

The Western Wall itself is actually the base of the Temple Mount, on which sits the Dome of the Rock and a Mosque considered one of the most holy in Islam. The Jews and many Christians believe that a third temple will one day be built. Already, Israel is in possession of either replacement artifacts, or the ancient relics themselves, once the third temple is built. 

What’s interesting is that HOW it’ll be build is still debated, with some Orthodox Jews believing that the Third Temple will be send down directly from God onto the mountain, destroying everything else on it. Pretty wild.
