Owing to the desire and wishes of the late Founder and Governor of Al Jouf region, His Excellency Amir Abdulrahman Al Sudairy (peace be upon his soul), the board of directors instructed that Al Rahmaniah Mosque be built in the main campus of the Centre at the heart of the Foundation. This mosque was established with the generous help and full support of King Fahd bin Abdul Aziz, (God bless his soul), and a number of additional donors. During the opening ceremony, the first Friday prayers were held on the 20th day of the month of Dhu Al-Hijjah in the year 1415AH (1995 AD). In capacity, the mosque accommodates up to two thousand and five hundred worshippers (2000 males in the men’s section and 500 females in the ladies section). The building relies on a natural cooling system where a number of cooling towers are used to provide cool air. The concept of using such a unique and environment friendly cooling system was adapted from an old traditional cooling method that was used in the Arabian Gulf region back in the old days. Al Rahmaniah Mosque is the first public establishment in the world to adapt such a cooling system, and has therefore become a popular destination for researchers and experts in this area of interest who visit this location because they are fascinated or wish to see and study this unique ancient-modern day technique.
