Edirne sits at the very western edge of Turkey, right near the borders with Bulgaria and Greece. Here is a look inside the city's "Old Mosque." In Turkey, "old" is relative, but in this case it means early 15th-century. When I walked in, I was greeted by a young man, practicing his English, who welcomed me. Then, taking his leave, he walked up stairs to a pulpit, picked up a microphone, and chanted the verses for this midday moment of prayer (one of five each day) that were broadcast throughout the city.
