İzmir stands as Turkey's third-largest city with a metropolitan population of 4,394,694 recorded in the 2021 census. The city occupies the head of the Gulf of İzmir on the Aegean Sea coast, positioned at coordinates 38.4237°N, 27.1428°E. The metropolitan area extends along 120 kilometers of coastline and reaches inland across the alluvial plain formed by the Gediz River delta. İzmir Province covers 11,891 square kilometers and includes seventeen metropolitan districts, with Konak, Karşıyaka, and Bornova forming the urban core. The city sits at the western terminus of the E96 highway connecting to Ankara, 550 kilometers distant, and serves as the primary port for the Aegean region. Adnan Menderes Airport, located 18 kilometers south in the Gaziemir district, handled 14.2 million passengers in 2019 before pandemic disruptions. The port of İzmir processed 38.4 million tons of cargo in 2020, making it Turkey's fourth-busiest port facility after Ambarlı, Mersin, and İskenderun.
The site has sustained urban settlement since approximately 3000 BCE, with archaeological evidence at Bayraklı indicating Bronze Age occupation. Greeks established Smyrna around 1000 BCE on the Bayraklı mound before relocating the city to its current peninsular location around 300 BCE under Lysimachus, one of Alexander the Great's generals. The Roman period brought prosperity from 133 BCE when the region became part of the Asia Province. An earthquake destroyed much of the city in 178 CE, after which Emperor Marcus Aurelius funded reconstruction. Byzantine control lasted until Seljuk Turks captured the city in 1076, though Crusaders briefly held it from 1097 to 1098. The Knights of St. John controlled Smyrna from 1344 to 1402. Ottoman Sultan Mehmed I permanently incorporated the city into Ottoman domains in 1415. The Greek population formed the majority throughout the 19th century, with Greeks, Armenians, Jews, and Levantines creating a cosmopolitan commercial center. The Great Fire of Smyrna burned from September 13 to September 22, 1922, destroying approximately 25,000 buildings in the Armenian and Greek quarters following Turkish military entry at the end of the Greco-Turkish War. Population exchanges mandated by the 1923 Treaty of Lausanne removed the Greek Orthodox population to Greece while Muslims from Greek territories arrived in İzmir.
The modern city operates Turkey's largest trade fair complex at the İzmir International Fair, established in 1936 and occupying 420,000 square meters in the Kültürpark district. The annual fair attracted 1.2 million visitors in 2019. The industrial base includes Petkim petrochemical complex at Aliağa, operational since 1965 with annual ethylene capacity of 600,000 tons. Tüpraş operates a refinery at Aliağa with processing capacity of 226,440 barrels per day. The free zone at Menemen, established in 1990, hosts 242 companies employing approximately 8,000 workers. Agricultural processing dominates the Kemalpaşa and Torbalı districts, handling grapes, figs, olives, and tobacco from the Gediz valley. İzmir produces approximately 40 percent of Turkey's seedless raisin exports, totaling roughly 120,000 tons annually. The metropolitan area contributes 6.2 percent to Turkish GDP according to 2019 economic data.
Konak Square forms the ceremonial center, marked by the Saat Kulesi clock tower erected in 1901 to commemorate the 25th anniversary of Sultan Abdülhamid II's accession. The tower stands 25 meters high with a German mechanism manufactured in the Stolberg workshops. The adjacent Yalı Mosque, built in 1755, features a single dome and a waterside location on reclaimed land. Kemeraltı Bazaar extends inland from Konak through a network of covered passages and open streets dating primarily from the 17th and 18th centuries, though the district has continuously hosted commercial activity since ancient times. Approximately 10,000 shops operate within the bazaar precincts. Kızlarağası Han, constructed in 1744, functions as a restored caravanserai now housing craft workshops and tea houses around a rectangular courtyard. Hisar Mosque, completed in 1597 under architect Kasım Ağa, represents the largest Ottoman-era mosque in İzmir with a central dome measuring 15 meters in diameter.
The archaeological site at Smyrna occupies the Kadifekale hilltop at 186 meters elevation in the Konak district, where Hellenistic and Roman city walls remain partially standing. The current fortifications date primarily from Byzantine reconstruction between the 4th and 14th centuries, incorporating ancient blocks in lower courses. The acropolis commands views across the modern city and gulf. Below the hill, the Agora of Smyrna preserves a Roman marketplace reconstructed after the 178 CE earthquake, with excavations revealing a basilica measuring 120 by 80 meters, three-story arcade porticoes, and underground vaulted galleries for storage. Eleven intact columns of the northern arcade still stand. The site museum displays reliefs and statuary recovered during excavations conducted between 1932 and 1941. Access requires a ticket costing 30 Turkish lira as of 2023.
Kordon refers to the waterfront promenade extending 5 kilometers from Konak through Alsancak to Karşıyaka ferry terminals, lined with apartment buildings from the 1920s and 1930s displaying neoclassical and Art Nouveau detailing. The pedestrian path accommodates approximately 50,000 daily users according to municipality counts. Gündoğdu Square, created in 1989 on reclaimed land, features a monument to Mustafa Kemal Atatürk unveiled in 1988 and an ornamental pool with fountain displays. The promenade continues through Cumhuriyet Meydanı, site of Republic Square redesigned in 1932, and past the historic Alsancak station building completed in 1858 for the İzmir-Aydın Railway, the first railway constructed in Ottoman Anatolia. Pasaport Pier serves ferry routes to Karşıyaka, with vessels making the 2.2-kilometer crossing in approximately 20 minutes at intervals ranging from 10 to 30 minutes depending on hour. ESHOT, the municipal transport authority, operates these ferries along with bus and metro services.

Pergamon, situated 105 kilometers north of İzmir near modern Bergama, preserves an acropolis at 335 meters elevation crowned by the Altar of Zeus, originally measuring 36.44 by 34.20 meters with a sculpted frieze depicting the Gigantomachy. The frieze sections were removed to Berlin between 1878 and 1886 where they remain in the Pergamon Museum. The foundation and partial reconstruction remain on site. The Library of Pergamon, constructed around 200 BCE, reportedly held 200,000 scrolls, making it the second-largest library in the ancient world after Alexandria. The theater, built into the hillside, features 80 rows of seats accommodating 10,000 spectators with a nearly 60-degree incline, among the steepest in antiquity. The Temple of Trajan, a white marble Corinthian structure from the 2nd century CE, occupies the highest terrace. The Asclepion, located 3 kilometers southwest of the acropolis, functioned as a medical treatment center founded in the 4th century BCE and expanded during Roman times. The physician Galen, born in Pergamon around 129 CE, studied and practiced here.
