There's lots of architecture worth looking at in Konya if you have the time and energy to seek it out. We were short on time, and inclement weather put a damper on things, but we did manage explore a few sights. This is the Sultan Selim mosque, created 1563-1564 by the great architect Sinan, who also designed the more famous Süleymaniye Mosque in Istanbul, which we visited (but couldn't photograph) at the end of our trip.
On the left, the main hall. On the right, the niche with microphone where the muezzin broadcasts his call to prayer five times a day. The chant they sing may be carried electronically these days, but it must be performed live.
