Archaeologists in İznik, Turkey, have uncovered a small hidden church located beneath the Church of the Holy Fathers [1].

The discovery is significant because the site may have hosted the First Council of Nicaea. This gathering served as a defining moment in the early development of Christianity [1].

The excavation revealed that the smaller church was situated directly under the existing structure of the Church of the Holy Fathers [1]. Researchers said the architectural layout and location suggest a link to the historical councils held in the region [1].

İznik has long been recognized as a center of early Christian history. The uncovering of a subterranean place of worship provides a physical link to the era when church leaders gathered to establish core doctrines [1].

While the site is now open to archaeological study, the team said it continues to analyze the structure to confirm its exact role during the council [1]. The findings add a new layer of physical evidence to the historical record of the region [1].

The identification of a physical site linked to the First Council of Nicaea provides historians with a tangible location for the debates that shaped orthodox Christian belief. If confirmed, this discovery transforms the Church of the Holy Fathers from a site of general historical interest into a primary landmark for the study of early ecclesiastical governance.
