When you ask a religious Jewish old man what Jerusalem means to him, you might hear the words from a song of ascents Of David (Psalm 122, 1-3) , which describes the 2000 years of desire to go back to Jerusalem where the "upper" and "lower" cities where united together: 

I rejoiced with those who said to me,
“Let us go to the house of the Lord.
Our feet are standing
in your gates, Jerusalem."
...

 If you ask a christian, he might show you the churches telling the gospel Passion story of Jesus in Jerusalem in the Final Ministry and the Apostolic Age, as recorded in the New Testament. And if you ask a Muslim, he will tell you the story of Islamic prophet Muhammad and his night visit in the Farthest Mosque and in the heaven in a single night.

The beauty of Jerusalem is unforgettable. The scenic views and mountains around, ultra ortodox and modern people on the streets,  stones and walls all over that tell you the stories from thousands years of history, stimulate any visitor to feel, to be impressed and to judge the city that was the subject of biblical poetry and wisdom over the ages.
