If one had but a single glance to give the world, one should gaze on Istanbul. ~Alphonse de Lamartine
Lefke Gate, Nicaea
The Lefke Gate, part of Nicaea’s city walls. Nicaea or Nicea was an ancient city in northwestern Anatolia, and is primarily known as the site of the First and Second Councils of Nicaea (the first and seventh Ecumenical councils in the early history of the Christian Church), the Nicene Creed (which comes from the First Council), and as the capital city of the Empire of Nicaea following the Fourth Crusade in 1204, until the recapture of Constantinople by the Byzantines in 1261.
The ancient city is located within the modern Turkish city of İznik (whose modern name derives from Nicaea’s). Image: wikipedia
