Saudi authorities have completed the third and largest expansion of the Masjid al-Haram in Mecca to increase the site's capacity [1].

This expansion is critical for managing the massive influx of worshippers during the Hajj, ensuring operational readiness and safety as the number of global pilgrims grows. The project aims to reduce congestion during the most crowded days of the Islamic calendar.

The Saudi Ministry of Hajj and the Saudi government finalized the project on the Monday preceding the Day of Arafah during the 2024 Hajj season [1]. This timing allowed the mosque to be fully operational before the main rites of the pilgrimage began [1].

According to official data, the expansion allows the mosque to accommodate more than 1,850,000 worshippers simultaneously [1]. At its absolute maximum, the capacity can reach approximately 2,000,000 people [1].

These infrastructure upgrades were necessary to handle the scale of the current pilgrimage. More than 1.5 million pilgrims have arrived from abroad for the 2024 Hajj season [1]. The increased space is designed to facilitate the movement of these millions of visitors, while maintaining the sanctity and order of the site.

The project represents the most significant growth in the mosque's history. By expanding the physical footprint, Saudi Arabia aims to prevent overcrowding, a persistent challenge for the holy city during peak religious windows.

The expansion allows the mosque to accommodate more than 1,850,000 worshippers simultaneously.

The completion of this expansion reflects Saudi Arabia's strategic focus on increasing the volume of religious tourism and pilgrimage. By raising the simultaneous capacity to nearly 2 million people, the government is attempting to mitigate the logistical risks associated with extreme crowd density, which has historically been a primary safety concern during the Hajj rites.
