Most North Americans usually don't see places of worship like this! They are big, beautiful, and loud. I hear the "Call to Prayer" (Azan) five times a day. The Azan or "Call to Prayer" should be looked at in a similar way to church bells. They both make a lot of noise, and do the job of keeping one religion, or another, on our minds. In Istanbul there are thousands of Mosques, you are always in earshot of one of my favorite things about this city... The Azan : )
