Where do muslim pilgrims travel to as part of their religion

   Mecca

Explanation:  The pilgrimage that represents one of the Five Pillars of the Islam or as it is called Hajj, implies that every Muslim who is rich enough at least once in his life goes to pilgrimage to Mecca, and worship Kaaba. Kaaba is a cube-shaped building that existed in the Arab world before the appearance of Islam, was dedicated to idols, but Muhammad cleansed this stone from idols and returned to it the original purpose of respecting one God who was established by Abraham. Kaaba e is located in the Great Mosque of Mecca in Saudi Arabia, and this city together with that mosque represents the holiest place in the world for Muslims.
