Once a dusty desert town, Mecca, in what is now Saudi Arabia, is today the real Mecca for Muslims. Other than being the foremost place of pilgrimage for Muslims worldwide, it is the cultural capital of the Islamic world and a true melting pot of worldwide Muslims. Mecca or Makkah, the holiest city in Islam, is the place where the Prophet Muhammad was born and raised, and is believed by Muslims to have received the first revelations of the Quran. And this is where the Kaaba is — in the centre of Islam's most sacred mosque, Masjid al-Haram, which is the direction that all Muslims from all over the world face when performing Islamic ritualistic prayer (salat).
Masjid al-Haram or The Grand and the Sacred Mosque, the largest mosque in the world, is visited by millions of Muslims throughout the year, especially during the last month of the Islamic calendar, to perform Hajj, the pilgrimage which is a mandatory religious duty for every Muslim who can afford it.
Muslims believe that the history of Mecca goes back to Abraham (Ibrahim) who built the Kaaba with the help of his eldest son Ishmael around 2000 BCE. In 570 CE, Muhammad was born in Mecca. Since those days, Mecca's history and identity has been inextricably linked with Islam.
