Temple Destroyed

This is a picture of the "Western Wall" in Jerusalem.  It is all that is left of the Jewish Temple that was destroyed by the Romans in 70 AD.  If I understand it rightly, it was not part of the Temple itself but the support of an extension King Herod made of the Temple courtyard.  It has become a sacred place of prayer for Jews today.  (The gold dome is Muslim.)
There is no building so essential to Christian religious practice.  Even the Kaaba in Mecca does not seem so important to Islam as the Temple was to Judaism.  It's destruction changed Jewish religious practice radically.  There was no more animal sacrifice and no more priesthood.
I wonder often what Judaism would be like today if the Temple had never been destroyed.  Would animal sacrifice still be part of Jewish religious practice as it was in the time of Jesus?  It is hard to imagine that it would.  The loss of the Temple forced Jews to find another way to practice their religion.  The Scriptures remained central to Jewish understanding of themselves.  The synagogue and the rabbi developed as institutions that gave Jews a way to maintain their identity.
At the very same time Jewish followers of Jesus were developing ways to be religious without the Temple.  There are indications in Matthew's Gospel, the most Jewish of the Gospels, that he saw the reform of Jesus as the best way to be true to his Jewish roots.
