As part of CNN's Leading Women series, Sheena McKenzie explores the work of Turkish architect Zeynep Fadillioglu - perhaps the first female architect to design a mosque, now on her third. In buildings where men and women are traditionally separated for worship, and women are often given a smaller space, Fadillioglu "purposely placed the women's section in one of the most beautiful parts of the light-flooded dome" in Istanbul's Sakirin Mosque. McKenzie concludes that although "Fadillioglu might have made a name for herself designing mosques, you don't needn't be religious to admire their beauty."
