Archaeologists think they may have found the lost Roman city of Julias, the home of three apostles of Jesus: Peter, Andrew and Philip (John 1:44; 12:21). A multi-layered site discovered on the northern shore of the Sea of Galilee, in the Bethsaida Valley Nature Reserve, is the spot, the team believes.

The key discovery is of an advanced Roman-style bathhouse. That in and of itself indicates that there had been a city there, not just a fishing village, Dr. Mordechai Aviam of Kinneret College told Haaretz. ... A key argument in favor of el-Araj being Julias lies in a mistake about the level of the Sea of Galilee, claim the archaeologists. 

Based on calculations by the excavators of nearby Magdala, most archaeologists assume that the level of the lake was 209 meters below sea level during the Roman period. They therefore assume that the site of el-Araj was under water until the Byzantine period. But either the ancient Romans had gills, or it wasn't.
