Sultan Mizan Mosque

This very large mosque in Putrajaya has a unique architechture. It's dome is made of stainless steel and the mosque itself is square in shape(optimum use of space) - thus creating an enormous hall. It is said that up to 20,000 people can be in the mosque at any one time. For that many people to squeeze in, I think all the spaces on the mezzanine floor and the corridors to the left, right and rear would need to be occupied.
The curves that are part of the design are necessary to soften the otherwise squarish design and works well - overall very pleasing to the eyes. Definitely a marvel, modern mosque to be admired.
