A quiet lakeside town gave the world a creed that shaped Christianity, then centuries later produced the dazzling tiles that clad the great mosques of Istanbul. This is the double story of İznik.
Few small towns carry as much history as İznik. Ringed by five kilometres of ancient walls on the shore of a serene lake, this was Nicaea — where in 325 AD the first great Council of the Christian Church met and produced the Nicene Creed, still recited by billions today. Centuries later, under the Ottomans, the same town became the workshop that produced the most beautiful ceramic tiles ever made. History here comes in two golden ages.
Nicaea: Where a Creed Was Born
The Roman and Byzantine walls, the monumental gates, and the ruins of the great churches recall İznik’s age as a capital of faith. Most hauntingly, beneath the lake’s surface lie the remains of the Basilica of St Neophytos — a sunken church discovered in the water, visible from the shore and the air, a ghostly reminder of the councils held here.
The Tiles That Clad an Empire
From the 15th century, İznik’s kilns perfected a brilliant white ceramic painted in cobalt blue, turquoise and a signature tomato-red under a glassy glaze. These İznik tiles line the walls of the Blue Mosque, Topkapı Palace and Hagia Sophia. Today a revived craft scene keeps the art alive, and you can watch artisans at work and buy directly from the studios.

What to See and How to Visit
See the İznik walls and Istanbul Gate, the Green Mosque with its early tilework, the Ayasofya (Hagia Sophia) of İznik where the councils are commemorated, and the lakeside at sunset. İznik is an easy day trip from Bursa or a scenic stop between Istanbul and the south.
