Masjid al-Haram, also known as the Great Mosque of Mecca, is the largest mosque in the world and surrounds the holiest site in Islam, the Kaaba. The mosque is at the heart of the annual Hajj pilgrimage and is also the destination for Umrah, the lesser pilgrimage throughout the year. The mosque's current structure covers an area of more than 88 acres, accomodating millions of worshippers during peak times. The mosque has undergone numerous expansions, the latest being under the Saudi Arabian government, which has increased its capacity and modernized its facilities. Within the mosque's precincts lies the Zamzam Well, a holy site believed to provide water with healing properties. Masjid al-Haram is a unique site that combines deep religious significance with architectural magnificence. The Kaaba, a cube-shaped structure at the center of the mosque, is the qibla, the direction Muslims face during prayer. The mosque includes various well-known features such as the Black Stone, the Maqam Ibrahim, and the Safa and Marwa hills. The ability to pray in the Haram is a deeply spiritual experience for Muslims, with the area being a sanctuary of peace.
