Amazing Mosque

We were walking around the city trying to get to our destination when we stumbled across this beautiful Mosque. It wasn't in any of our travel books so unfortunately I don't know any of its history but I think it is of the prettiest Mosques I have ever seen. At first I didn't think it was a working Mosque but then when we walked a bit further around it we saw there were some Muslim teenagers in the courtyard so I guess it is still used. I am not Muslim nor do I worship in a Mosque but I can appreciate beauty when I see it. I hope you can as well.
