Jerusalem is a pilgrimage site because it is "The City of God" for both the Christians and Jews. It is the original site for Solomon's Tabernacle. It is also the location of the crucifixion of Christ and his resurrection. Millions worldwide who are believers or Christian/Jewish people dream of being able to go to Jerusalem and to go to the wailing wall, which is part of the foundation of the tabernacle.
Jews will get the tabernacle or rather temple rebuilt in the future. This is a goal of both Jews and Christians. And it will be located in Jerusalem.
While Judaism does not mandate pilgrimage to any site, many Jews willingly make the pilgrimage to the Western Wall because of the holiness with which Jews see the site.
