Undoubtedly, the most well-known structure of the Green Complex is the Green Tomb, which was built for Çelebi Mehmed and is known for the color of the green and turquoise relief tiles that adorn its facades. It was built in 1421 by Çelebi Mehmed, the son of Yıldırım Beyazid and the fifth of the Ottoman sultans. Located in the Yeşil district, the mosque was built in 1419 by Çelebi Sultan Mehmed. Yeşil Mosque, which is one of the mosques with an “inverted T” plan, is one of the most beautiful historical structures of Bursa as well as our country. The architect of the mosque is Hacı İvaz Pasha. The crown gate at the entrance of the Yeşil Mosque is a beautiful product of Turkish stone carving. The muqarnaslı life is of extraordinary beauty. Green stone and marble are used in the door arch. There are two windows on the right and left of the stone door, and an outer altar between them. Very fine stone work is seen in these as well. One of the most perfect examples of tile workmanship in the mosque is its altar, which is more than ten meters high. The mihrab, which contains flowers with various geometric motifs, is one of the most beautiful places in the mosque. It is possible to see the best examples of woodworking in Bursa in this mosque. Window covers are good examples of woodworking of the period. There are very fine ornaments on its sliced domes, which cannot be found in other mosques. There is a beautiful fountain inside the mosque. The fountain of the fountain, which is made of one piece, is of unique delicacy.
