Prophet's Mosque Expansions In Saudi Arabia Boost Comfort And Capacity For Millions Of Worshippers

The Prophet’s Mosque now accommodates about 1.8 million worshippers, making it one of the world’s largest mosques. Successive Saudi projects have expanded prayer areas, modernised facilities, and improved access, while keeping the mosque’s traditional Islamic design and spiritual environment central to every stage of development and planning.

These projects reflect a long policy of care for the two holy mosques that began under King Abdulaziz bin Abdulrahman Al Saud. Saudi Arabia’s leadership has treated the expansion and maintenance of the Prophet’s Mosque as a continuing national responsibility in service of Islam and visitors worldwide.

The third Saudi expansion of the two holy mosques, launched in 2012 (1433 AH), is the largest for the Prophet’s Mosque in the Saudi era. This phase focused on surrounding courtyards, service buildings, and infrastructure, designed according to updated engineering standards to serve the increasing numbers of worshippers.

The 2012 project added wide passages, shaded squares, and new prayer areas within and around the Prophet’s Mosque. Facilities and access routes were designed to support people with disabilities, while modern amenities were introduced to improve comfort and movement without affecting the mosque’s religious atmosphere or architectural identity.

Under the Custodian of the Two Holy Mosques King Salman bin Abdulaziz Al Saud, work on completing the third Saudi expansion has continued. King Salman ordered the continuation of construction and inaugurated major development schemes, confirming that the project remains a national priority for the current Saudi leadership.

King Salman’s supervision builds on approaches set by previous Saudi rulers, who gave constant attention to the two holy mosques. Their policies centred on increasing capacity, improving services, and protecting the religious and historical status of the Prophet’s Mosque for visitors and worshippers from different countries.

Earlier Saudi expansion stages of the Prophet’s Mosque

The first Saudi expansion of the Prophet’s Mosque started in 1952 (1372 AH) and ended in 1955 (1375 AH). During this phase, around 16,326 square metres were added. The enlarged area raised the mosque’s capacity to nearly 28,000 worshippers, supporting growing visitor numbers at that time.

A second major expansion began in 1985 (1406 AH) and finished in 1994 (1414 AH), covering the main building, roof, and surrounding open courtyards of the Prophet’s Mosque. When this stage concluded, the total mosque area reached about 300,000 square metres, with space for roughly 698,000 worshippers.

The third Saudi expansion is described as the biggest development in the history of both the Grand Mosque and the Prophet’s Mosque. Its scale supports large crowds in peak seasons, by combining expanded capacity with infrastructure that organises movement in and around the entire mosque site.

Through these successive stages, the Prophet’s Mosque has grown into a complex that welcomes millions of visitors year-round. The site now brings together historical depth, traditional Islamic architecture, and modern service systems, showing how Saudi projects have aimed to meet religious needs while managing increasing pilgrim numbers.
