Mosque with the green door

I found a beautiful green door, and the wall and minaret behind made it obviously a mosque. I knocked, and the guardian let me in. It was so pretty - not like the more stark and simple mosques of Old Islamic Cairo, this was decorated on every surface. It had simple marble columns throughout, and at the base of each column was a puddle of pale green worry beads for people praying to use. In fact, they are used like a rosary, and are very similar in form. I took about forty photographs. Every wall was tiled and there would have been twenty different designs. The mithrab was marble with twisting borders of inlaid stone flowers, the walls had stone carved borders at the highest edges, the ceiling was either pure white domes - at least fifteen - or beautiful dark carved and stained wood.
