Answer 1
Because all three religions have spiritual connections to it.
Answer 2
If you meant the question as phrased, it is based on an incorrect belief. The three most dominant Eastern Faiths are Hinduism, Buddhism, and Daoism and none of those (as well as Shintoism, Animism, and Ancestor Worship) have any connection to Jerusalem and have never made assertions to that effect. If you meant to say the 'three Western Religions' then, yes, Judaism, Christianity, and Islam all have connections to Jerusalem. See the link below for a detailed description.
Jerusalem !
The City of the Prophets. Revered by Muslims as such. When Muhammad (peace be upon him) received the first revelation, the orientation of our prayers was towards Jerusalem. It was only later that God commanded the Muslims to then turn towards the House of Abraham, in Mecca.
When Muhammad experienced the Night Journey and Ascension to Heaven, he was transported to Jerusalem - to the Temple Mount - from where he ascended. He lead the prayers. with all the Prophets that had come before him.
Travelling to visit three and only three mosques is condoned, by Muhammad: the House of Abraham in Mecca, the Prophet's Mosque in Medinah, and the Al-Aqsa Mosque in Jerusalem. Prayer, in the mosque in Jerusalem, is considered 500 times more worthy of blessings than praying in any other mosque (except in Mecca and Medinah where the blessings are even greater).
AnswerThe above explains the Islamic connection.For Judaism, Jerusalem was the capital of Israel and then the southern Kingdom of Judah after the country split and was the site of the Temple of Solomon, where the Jews believed God dwelt Hence it is a sacred city for Jews.
For Christians Jerusalem was the site of the trial, crucifixion and resurrection of Jesus Christ,and this connection makes it holy.
In Judaism:
Judaism: It is where their ancient temples stood.
Christianity: It is where the Passion Of the Christ took place.
Islam: It is where Muhammad is said to have visited Heaven.
Jerusalem is considered holy by all three religions.

Hindus, Bhuddists, Animists and all the other major religions have no special regard for Jerusalem.
