In a remarkable discovery that bridges nearly two millennia of history, the ruins of an ancient Christian church have been unearthed beneath the waters of Turkey’s Lake Iznik — the site of the historic city once known as Nicaea. The church, believed to have been constructed around 390 AD, had remained submerged and forgotten for more than 1,600 years until modern archaeological efforts brought it back to light.
Lying approximately ten feet below the surface and some 160 feet from the shore, the submerged structure offers a rare and intimate glimpse into early Christian architecture and devotion in one of the faith’s most significant historical centers. Nicaea, of course, is renowned as the location where the First Council of Nicaea convened in 325 AD, producing the Nicene Creed that remains foundational to Christian theology.
Professor Mustafa Şahin, head of archaeology at Bursa Uludağ University, expressed his astonishment at the find. “When I first saw the images of the lake, I was quite surprised to see a church structure that clearly,” he said. Having conducted field surveys in Iznik since 2006, Professor Şahin noted that he had not previously encountered such a magnificent structure in the area.
Experts believe the church was erected in honor of Saint Neophytos, who was martyred in 303 AD at the site. According to Professor Şahin, the location may hold deeper historical layers: the Christian building is thought to have been constructed atop the remains of a pagan temple dedicated to Apollo, the Greek and Roman sun god occasionally associated with Jesus in the transitional period of early Christianity.
The church stood for centuries until a devastating earthquake in 740 AD razed the structure. In the aftermath, the ruins gradually sank beneath the rising waters of the lake, where they were preserved in a submerged state until their rediscovery.
Since 2015, archaeologists have been meticulously excavating the underwater site using a sophisticated system of powerful vacuum nozzles. These tools carefully remove sediment from around the ruins and transport it to the shore for detailed sifting, allowing researchers to recover and analyze artifacts while preserving the fragile context of the submerged monument.
The discovery has generated considerable excitement among both scholars and local authorities. Professor Şahin, together with local government leader Alinur Aktaş, has proposed transforming the site into Turkey’s first underwater archaeological museum. If approved, construction of the museum could begin as early as this year, with an anticipated opening to visitors in 2019. Such a facility would not only protect the ancient remains but also offer the public a unique opportunity to explore this extraordinary piece of Christian and Byzantine heritage in situ.
This submerged church stands as a powerful testament to the enduring legacy of early Christianity in Anatolia. Its revelation after more than sixteen centuries underwater serves as a vivid reminder of how history can remain hidden in plain sight — or, in this case, just beneath the shimmering surface of a tranquil lake — waiting for the right moment and the right technology to be brought back into the light.
