Mecca — al-Masjid al-Haram
BY THE NUMBERS · 1.5 billion faces turned · 2.5 million hajjis at peak
The largest mosque on the planet — 356,000 m², holding up to four million worshippers at peak Hajj. Entry is Muslim-only: the boundary sits 40 km from the centre. Pilgrimage requires ihram, an advance visa and registration via Nusuk.sa. Twice a year this is the largest peaceful crowd on Earth.
