The İznik Roman Theater, constructed in the 2nd century AD, undergoes restoration for tourism purposes in the İznik district of Bursa. Statement made by the Metropolitan Municipality, the İznik Roman Theater, which was established in 316 AD by Antigonius Monophthalmos, one of the commanders of Alexander the Great from Macedonia, still carries visible traces of the civilizations of Bithynia, Rome, Byzantium, Seljuk, and the Ottoman Empire. Sponsored by the Bursa Metropolitan Municipality since 2015, excavation works have been ongoing in the district, and the theater is among the most magnificent surviving Anatolian structures from the Roman period. Built on a flat area and elevated with vaults, making it the only example of its kind in Türkiye from an architectural perspective, it is known that the theater was commissioned by Roman Emperor Trajan to Pliny the historian and writer, who served as the Governor of Bithynia. The theater, which once hosted gladiator fights, was later used as a religious space after the prohibition of theater following the rise of Christianity. Damaged in the major earthquakes of 358, 362, and 368, the structure was repaired and some of its parts were dismantled for the strengthening of the city walls as İznik's defense. Excavations in the Roman Theater began in 1980 with the permission of the Ministry of Culture and Tourism. Since 2015, the excavation works have been carried out by a team led by the Department of Archaeology at Dokuz Eylül University, with the involvement of the Metropolitan Municipality. The excavations, led by Assoc. Prof. Dr. Aygün Ekin Meriç from the Department of Archaeology at Dokuz Eylül University, are conducted under the presidency of the İznik Museum Directorate.
