Trabzon is a vibrant Black Sea port city in northeastern Turkey, set between lush green mountains and the deep blue sea. Once the capital of the Byzantine Empire of Trebizond (1204–1461), the city retains extraordinary heritage—most famously the Hagia Sophia of Trabzon and Atatürk's mansion—while thriving today as a regional commercial hub. The surrounding highlands shelter alpine meadows, rushing rivers, and the iconic Sumela Monastery carved into a cliff face, making Trabzon a gateway for both history lovers and outdoor adventurers.
