Turkey occupies 783,356 square kilometers spanning two continents, with 97 percent of its landmass in Anatolia and 3 percent in Thrace across the Bosphorus Strait. This positioning grants access to eight countries by land border and four seas: the Black Sea to the north, the Aegean Sea to the west, the Mediterranean Sea to the south, and the landlocked Sea of Marmara connecting the first two through the Bosphorus and Dardanelles straits. Ankara serves as the capital with a population exceeding 5.6 million, while Istanbul holds approximately 15.8 million residents as of 2023 census data, making it the largest city straddling Europe and Asia at the Bosphorus waterway. The elevation ranges from sea level along 8,333 kilometers of coastline to Mount Ararat at 5,137 meters near the Armenian border, creating climatic zones from Mediterranean warmth in Antalya to continental extremes on the Central Anatolia Plateau where winter temperatures in Ankara drop below minus 10 degrees Celsius.
