Bursa it seems has more mosques and tombs than any other city in Turkey and in this city we visited the Bursa Ulu Camii and the Yeşil Türbe. The Green Mosque unfortunately was closed. We also made a stop at Koza Han to check out the famous Bursa ipek (silk). Read more about Bursa Ulu Camii Here. Read more about Bursa Yeşil Türbe (Green Tomb) Here.
