Within Judaism, the Temple in Jerusalem was the center of the Jewish religion, until its destruction in 70 CE, and all adult men who were able were required to visit and offer sacrifices known as the korbanot, particularly during Passover, Shavuot and Sukkot.
Following the destruction of the Second Temple and the onset of the diaspora, the centrality of pilgrimage to Jerusalem in Judaism was discontinued. In its place came prayers and rituals hoping for a return to Zion and the accompanying restoration of regular pilgrimages (see Jerusalem, Jews and Judaism).
Until recent centuries, pilgrimage has been a fairly difficult and arduous adventure. But now, Jews from many countries make periodic pilgrimages to the holy sites of their religion.
The western retaining wall of the original temple, known as the Wailing Wall, or Western Wall remains in the Old City of Jerusalem and this has been the most sacred site for religious Jews. Pilgrimage to this area was off-limits from 1948 to 1967, when East Jerusalem was controlled by Jordan.
Some Reform and Conservative Jews who no longer consider themselves exiles, still enjoy visiting Israel even if it is not an official "pilgrimage."
