Jerusalem is considered the holiest city not only in Judaism and Christianity but also in Islam.
It is believed that prophet Solomon built his temple (that was destroyed later on by the Romans) in Jerusalem.
However, the city of Jerusalem is also central to Christianity where prophet Jesus was living.
It is also central for Muslims as it was the first direction that they face during prayers and prophet Muhammad was raised to the Heavens (during the miracle of Israa and Mii'raaj) from Al-Masjid Al-Aqsa located in Jerusalem and returned back on the same night.

All three Abrahamic religions, Judaism, Islam, and Christianity, claim Jerusalem to be the holiest city in the Holy Land. This causes conflict. FYI ,the Jews were delivered by God into the land of Canaan; Jesus's life took place there; Mohammad is said to have been transported there during al-Isra wal-Miraj.
