The Western Wall. God is worshiped, not the Wall itself.
The western wall is the most holy thing for the Jews ( and even for some chrostens because the western wall is a part of the Jewish temple ) . Because the western wall Jerusalem is holy for the Jews, this is the most holy city for the Jews .
The Jews put prayers &notes in the cracks
It is a remnant of the holy temple. It is a holy site and Jews go there to pray. Often, people celebrate bar mitzvah's at the Western Wall.
There is no special time of the year for Jews to go to the Western Wall. Of course, there are usually more people there on holidays, but holidays occur throughout the year.
It is the remaining vestige of the Holy Temple.
The Western Wall (or Kotel).

the western wall/ the wailing wall/ the Kotel
There are a number of Jews who make the pilgrimage to visit the Western Wall, but there is no requirement for Jews to visit the Western Wall once in their lives (in comparison to Islam where a pilgrimage to Mecca is required once in someone's life).
There is no such thing as a wailing wall. This is a misnomer imposed by non-Jewish people who misunderstood the dinstinctive style of Jewish prayer, and thought it was wailing. Also, the wall is not scared of Jews, but it is sacred to Jews because it is the last remnant of the outer retaining wall of the ancient Temple.
