Mardin, Turkey ----- Mardin has often been considered an open air museum due to its historical architecture. Most buildings use the beige colored limestone rock which has been mined for centuries in quarries around the area.
If you get a chance to visit Istanbul city dont forget to go and see those reflective stones. People named this as The Stone Mirror. In this picture the way the stone mirror reflected that building really amazes me. Definitely want to get there one day!
