This 14th-century mosque has a needle-like minaret that boasts fine carvings. If you're interested in mosque architecture, plenty more mosques are in town to explore, and most of them are strung out along Cumhuriyet Caddesi. 

From the Şehidiye Mosque, head east along the road for about 200 meters and you'll arrive at the bulky, golden-stoned Melik Mahmut Mosque, which also dates from the 14th century. Or head west for approximately 400 meters and you'll come to the Ulu Mosque.
