Niceia – local do Primeiro e do Sétimo Concílio Ecumênico (325 e 787)

All traditions

Por que este destino é importante

İznik é a antiga Niceia, onde em 325 d.C. o Primeiro Concílio Ecumênico se reuniu e o Credo Niceno foi formulado – o mais antigo credo vinculante de toda a cristandade, ainda rezado em cultos ortodoxos, católicos e anglicanos.

Em 787 d.C., o Segundo Concílio de Niceia se reuniu aqui, encerrando a querela iconoclasta e restaurando a veneração de ícones.

O Papa Leão XIV visitou İznik em 28 de novembro de 2025, por ocasião do 1.700º aniversário do Concílio de Niceia.

Dicas para peregrinos

💡 Dicas para peregrinos

  • Iznik is comfortably visited as a day trip from Istanbul (140 km, 2 hours by road via Yalova ferry, or 3 hours via the highway). Most pilgrim groups depart Istanbul at 07:00 and return by 19:00.
  • Pope Leo XIV visited Iznik on 28 November 2025 for the 1700th anniversary of the First Council. Commemorative events continue through 2026; check the Vatican calendar and the Ecumenical Patriarchate website for current schedules.
  • The Hagia Sophia of Iznik (Iznik Ayasofyası) is an active mosque since 2011 — visit outside prayer times, dress modestly, remove shoes. Some scholars place the Second Council of Nicaea (787, restoration of icons) here; the building's archaeological history is itself disputed.
  • Walk the city walls (5 km circuit, mostly intact Roman-Byzantine masonry with later Ottoman additions) for the best perspective on the ancient council city. The Lefke and Yenisehir gates are the most photogenic.
  • Lake Iznik's southern shore was the likely site of the 325 imperial palace (now under water; underwater archaeology has located submerged remains). The lakeshore monuments to the First Council mark the modern pilgrimage focal point.
  • Iznik tile (Iznik çinisi) is the famous Ottoman ceramic tradition (the blue tiles of the Sultan Ahmed Mosque). The Iznik Foundation workshop near the city centre offers tours of the kilns and tile workshops — pair the council site with the ceramic heritage for a full day.

  • The Nicene Creed, recited every Sunday in Catholic, Orthodox, Anglican and most Protestant churches, was promulgated at Iznik on 19 June 325 AD. Approximately 318 bishops attended; 17 were martyrs who survived the Diocletianic persecution of 303-311.
  • Saint Nicholas of Myra (the historical Santa Claus) was almost certainly present at the First Council of Nicaea. The famous tradition that he slapped Arius the heretic in the face during the debates is a later legend, but the iconographic tradition is well-established.
  • The Second Council of Nicaea (787 AD) restored the veneration of icons after a century of Iconoclasm. The dogmatic definition — that icons are venerated (proskynesis) but not worshipped (latria), with worship reserved for God alone — is the foundation of all Orthodox and Catholic theology of the image.
  • Iznik was the temporary capital of the Byzantine Empire from 1204 to 1261, when the Latin Crusaders held Constantinople. The 'Empire of Nicaea' under the Laskaris dynasty preserved Byzantine continuity for 57 years and reconquered Constantinople in 1261.

Biblical references

  • Acts 16:7 — “After they had come to Mysia, they tried to go into Bithynia, but the Spirit did not permit them - the region of Bithynia includes the area around Iznik.
