I wouldn't call it the birthplace of religion, but Jerusalem has played an important role in 3 major religions, which are (in chronological order) Judaism, Christianity, and Islam. None of these religions actually were born in Jerusalem.
Jerusalem
Birthplace of Jesus
Bethlehem is also known as the City of David, because it was the birthplace of King David.
Jerusalem the birthplace of Christ
There is no one religion in Jerusalem. There are three main religions prevalent in Jerusalem, which are Judaism, Christianity, and Islam.

There is no such thing as the "Jerusalem Religion". Jerusalem is a city, not a set of beliefs. Although Judaism, Christianity, and Islam all hold Jerusalem to be sacred, none of these religions was founded in Jerusalem.
it was JESUS' birthplace and also great history and the Middle East
There is no such thing as the Jerusalem Holy Book. Jerusalem is a place, not a religion.
