Iranian photographer Mohammad Reza Domiri gives us an opportunity to see the entirety of these incredible spaces all at once. His fully panoramic, expansive photographs of centuries-old mosques reveal the genius of their geometries and complexity. The effect is dizzying in a different way, like some kind of fractalized religious hallucination.

There are some jaw-droppingly beautiful images in here.

Also, you may want to check out this Flickr search with many more equally-amazing pictures of the Mosque-cathedral of Córdoba, Spain, an Islamic mosque from the Middle Ages that was later converted into a Catholic Christian church, but still keeps most of its Moorish heritage intact:
