Mecca is an annual destination for approximately 2.5 million pilgrims who travel there to perform the Hajj, one of the Five Pillars of Islam. Located in Saudi Arabia, Mecca is considered the holiest city in Islam and is the birthplace of the Prophet Muhammad. The Hajj is a religious pilgrimage that every able-bodied Muslim is required to undertake at least once in their lifetime, and it involves a series of rituals that take place over several days. These include circling the Kaaba, a cube-shaped structure in the center of the Great Mosque of Mecca, and standing on the plain of Arafat. Mecca is a significant destination for Muslims worldwide and holds great religious and cultural importance.
