Here's a picture of the largest mosque in Dubai. All the mosques were quite impressive, of course, as a female and non-Muslim I wasn't permitted to enter. Though there are specific mosques just for women.
One thing that was interesting to me are the robes worn by both men and women. Men wear all white and women all black...many women had their faces covered. There was a warning in the guide book suggesting it was not wise to take photos of them in their traditional garments.
