Mosques throughout the Muslim world have some of the most intricate and exquisite architecture ever created by mankind. There's too much amazing architecture in them to cover in just one post, so we decided to focus simply on the mosque's ceilings – something the faithful might see when they look up to the heavens.

These images show just how heavily mathematics and geometry featured into Islamic architecture in the Arab world and elsewhere. The repeating perfect spirals and geometric forms are reminiscent of the intricate mandalas found in Buddhist art as well.

Iran is known for its extraordinary collection of stunning mosques, which we wrote about here, but there are beautiful mosques elsewhere as well. We'd love to see your photos of amazing mosque ceilings submitted below and invite you to vote for your favorites!
