Archaeologists uncover ancient baptistery in France tied to early Christian rituals

Fabien Blanc Garidel, the supervising archaeologist on the project, confirmed the discovery to Fox News Digital.

In an email translated from French to English, the historian described the baptistery as a "circular building, likely surrounded by a colonnade and covered."

Blanc Garidel noted that "at the center, the baptismal font is octagonal on the outside and cross-shaped on the inside. It is bordered by a decorative coating made of béton de tuileau, a Roman concrete using crushed tile."

Blanc Garidel estimated the baptistery to be 1,500 to 1,600 years old. 

It is located in front of the forecourt of the cathedral, which was a common layout at the time.

Pictures show archaeologists working near the ancient cross-shaped structure. 

The foundation of the baptistery, Blanc Garidel said, is the only relic that remains - but the font, or the baptism receptacle, is "in very good condition."

He said the recent excavation helps show how early the diocese of Vence was established.

"This discovery confirms the antiquity of the bishopric of Vence and enhances our knowledge of early Christian religious practices in the Alpes-Maritimes and Provence," he said.

"However, much work and analysis remain to be done in the coming months to provide further details."

Several burials were uncovered in the cathedral's nave, he also said. 

The tombs were built using pitched Roman roof tiles, a method typical of the time.

"All of these burials are likely those of religious figures (bishops or canons) from the Carolingian period," he said. 

"Radiocarbon dating will help clarify the timeline."

Overall, the archaeologist said, the excavation sheds light on over six centuries of construction - and even revealed a Roman dwelling under the cathedral.

"The cathedral was demolished in the 11th century to build a new one right next to it."

"After it was abandoned, two bell molds were installed in the nave of the old cathedral - likely to cast bells for the new one."

The discovery is among several recent finds offering new insight into early Christianity in Europe.
