The Wikipedia tells us about Trabzon:
"Trabzon (Greek: Τραπεζούντα, Trapezounta, Armenian: Տրապիզոն), historically known as Trapezus and Trebizond, is a city on the Black Sea coast of north-eastern Turkey and the capital of Trabzon Province. Trabzon, located on the historical Silk Road, became a melting pot of religions, languages and culture for centuries and a trade gateway to Iran in the southeast, Russia and the Caucasus to the northeast.[1] The Venetian and Genoese merchants paid visits to Trebizond during the medieval period and sold silk, linen and woolen fabric; with the latter having an important merchant colony within the city that was similar to Galata near Constantinople (across the Golden Horn) in present-day Istanbul.[2] Trabzon formed the basis of several states in its long history and was the capital city of the Empire of Trebizond between 1204 and 1461. During the Ottoman period, Trabzon, because of the importance of its port, became a focal point of trade to Iran, India and the Caucasus. The population of the city is 230,399 (2009 census)."
