Ca’ Foscari University of Venice announced the discovery on October 15 following excavations conducted in 2025 and 2026. Researchers believe the findings provide archaeological evidence supporting historical accounts of Christianity in the region.
The church, measuring approximately 98 by 66 feet, dates between the late fourth and early fifth centuries. Its eastward orientation and architectural features resemble other early Christian structures in the northern Adriatic region.
St. Jerome’s Letter 60 describes the church and the ministry of Nepotian, a young priest serving under Bishop Heliodorus. Excavations also revealed a substantial building believed to be the bishop’s residence, featuring multiple rooms and possibly two floors.
Researchers suggest the reuse of ancient Roman road materials in the foundations reflects the growing civic influence of Christian bishops during this period.
