Istanbul Tours

Step back in time and discover Iznik (ancient Nicaea), one of Türkiye's most remarkable historical and cultural treasures, on this full-day private tour from Istanbul. Accompanied by your professional licensed guide, explore a city that flourished under the Roman, Byzantine and Ottoman Empires and played a pivotal role in the history of Christianity.

Iznik is one of the world's most significant Christian heritage destinations. It hosted the First Council of Nicaea in 325 AD, where the foundations of Christian doctrine and the Nicene Creed were established, and the Second Council of Nicaea in 787 AD, which restored the veneration of icons. These landmark events made Nicaea one of the most important pilgrimage sites in Christian history.
