Berliner Boersenzeitung - Turkey basilica emerges from lake, illuminating early Church life

Now, the church in Iznik, a small town several hours from Istanbul, stands on dry land, its ruins exposed as the waters that engulfed it for more than 700 years have receded due to climate change.

Known as the Basilica of the Holy Fathers, it marks the site of one of the early Church's most important gatherings which took place in Nicaea 12 years after the Roman Empire legalised Christianity, ending years of persecution, torture and death.

In AD 325, Constantine the Great convened the First Council of Nicaea, a gathering of 318 bishops who, after two months of intense debate, drafted the Nicaean Creed, a statement of faith still central to Christianity.

Pope Leo XIV's visit to the basilica on Friday marks the Council's 1,700th anniversary.

Overlooking the site from a viewing platform, archaeologist Mustafa Sahin, who first identified it from aerial photos in 2014 and has led the excavation -- the first six years of which were underwater -- said his team had established that the basilica was built in AD 380.

"When it was first discovered, the ruins were 50 metres (164 feet) offshore and two metres underwater," explained Sahin, a professor who heads the archaeology department at Uludag University in the nearby city of Bursa.

"However, due to global warming, the lake's water started receding in 2020 and now the entire church is above the water."

- 'A martyrs' graveyard' -

The basilica stands on the site of an earlier church built where a 16-year-old called Neophytus was killed for his faith in AD 303, during an era of fierce Roman persecution, Sahin said.

Whipped and stoned, Neophytus was eventually beheaded "for refusing to offer sacrifices to pagan gods and worship idols", according to the site's small but informative museum explaining the history of Christians in Nicaea, once an important Roman city.

That wooden church hosted the First Council, but did not survive a 9.0 magnitude earthquake in AD 358. The basilica was built on the same site around 20 years later.

It stood for seven centuries until it too was destroyed in an earthquake in 1065, with the ruins swallowed up by the lake's rising waters some two centuries after.

It was not just Neophytus who was buried there: Sahin's team has uncovered evidence of multiple violent deaths, describing the church as "a martyrs' graveyard".

"So far, we've determined there are around 300 graves," he said, pointing to the terracotta tile tombs denoting burial sites. Under one, two visibly broken bones were visible alongside a partial jawbone with teeth.

"We have excavated only 27 of these graves and have observed signs of torture -- broken arms and legs, skulls with holes in them, perforated craniums, showing us that those buried here were tortured and killed," he said.

One area stands out for its much smaller grave covers.

"There are 11 children's graves. We haven't opened them yet but we know they were children because of the size," he explained.

Anthropologists will carefully excavate, analyse and document the bones before returning them to their resting place, he said.

"This was not just a regular church cemetery but rather a place of martyrdom, a very significant church for Christians."

- Turkey key to Christian history -

Iznik's mayor Kagan Mehmet Usta is hoping Leo's visit will bring much greater recognition to this town of 45,000 residents, which has fortified walls dating back two millennia and hopes to become a pilgrimage site.

"Since his visit was announced, Catholic and Orthodox Christians have already started visiting Iznik and we think that will increase after he comes," he told AFP, admitting it was "impossible" to guess how many would come for Leo's visit.

For Sahin, Turkey is central to Christian faith because it has so many well-preserved structures that tell the story of the early Church.

"Christianity emerged as a religion around Jerusalem, but if Anatolia -- today's Turkey -- did not exist, there would be no Christianity," he said, referring to the travels and letters of the apostle Paul, which make up the bulk of the New Testament.

"The pope's visit here is very important -- this area will become a pilgrimage site for Christians. In terms of faith tourism, it will be a great opportunity for Turkey."
