A basilica remain was discovered under Lake İznik in 2014. It has an interesting historical background. It was a basilica that was built 1600 years ago. It was collapsed through the lake due to the earthquake. This zone has been on a dangerous earthquake line and it is still available for today.

It was realized that it was dedicated to St. Neophytos who was murdered by Roman soldiers. But his body couldn’t be found because his body was removed. Because the grave was open.

It is thought that there used to be a pagan temple under the basilica and it is older than the basilica. This study will be done to discover the history of this area.
