A mosque built for the park's sun
The Grand Mosque is the main place of worship in King Salman Park. Freyssinet Saudi Arabia lists it with a 16,153 m² built-up area, room for 3,900 worshippers and a 66 m minaret, a passively cooled basement and a roof fitted with photovoltaic panels. WSP is the consultant.
One package, three works
The same contract also covers the Arabian Garden (85,552 m²), Hub 3, Gate 4, District 3, a fourth tunnel and underground parking of 29,408 m² for 705 cars. Freyssinet gives the contract value as SAR 1,253,801,073, with a start on 20 October 2024 and a duration of 22 months. That timetable would point to about August 2026, but we have found no completion announcement.
Who designed it
RIBAJ names Mangera Yvars Architects, a London and Barcelona practice, as the mosque's architect and saw it clad in scaffolding at the end of 2025. The practice says it worked on two assets in the park, and MEED places the Arabian Gardens next to the mosque.
Not the Diriyah mosque
Please do not confuse it with the King Salman Grand Mosque in Diriyah, a separate project with a capacity above 10,000 worshippers.
A note on the name
The Foundation's pages we read do not name a Grand Mosque, and no Arabic source gives an official name. "الجامع الكبير" is the common rendering and we will update it once the Foundation confirms its naming.

Under construction as of the end of 2025, the latest date we can source. It is not open.
