Nehalennia is a goddess of unclear origin, perhaps Germanic or Celtic. She is attested on and depicted upon numerous votive altars discovered around what is now the province of Zeeland, the Netherlands, where the Schelde River flowed into the North Sea. Worship of Nehalennia dates back at least to the 2nd century BC, and veneration of the goddess continued to flourish in northern Europe in the 2nd and 3rd centuries AD.
