A couple of years ago I learned about the little know Dutch Goddess of the North seas, Nehalennia. Since my main deities are Gods and Goddesses of the seas I had to dive into who this Goddess is and her importance. Nehalennia is the Goddess of the North seas, Sailors, fortune at sea, safe passage at sea and sometimes considered a Goddess of life and death. She is also considered to be a Mothergoddess. So in many ways you can see similarities between Nehalennia and the Norse God Njordr, Ægir and the Goddess Rán. I always like to give lesser known Gods and Goddesses the spotlight they deserve and Nehalennia definitely deserves such honor.
In 1645 a large part of the Zeeland Dunes in Domburg were eroded due to a huge storm. What they found were altarstones or votive stones dedicated to the Goddess Nehalennia. These stones dated back to the second and third century BC. They also find the remains of a Temple. Which suggests that there once was a Temple dedicated to Nehalennia there. Although it is still not known whether this Goddess was Celtic or Germanic, it is known that the Romans in the area worshipped this Goddess. The texts on the votive stones are in Latin. Therefore it is thought that Nehalennia is the name the Romans gave to the Goddess. The stones found in Domburg were displayed in the church, which turned into a sort of museum. However in 1848 lightning struck the church tower, burning it to the ground. Most stones were destroyed.
In 1970 a fisherman at Colijnsplaat in Zeeland noticed four large stones in his fishing net. He decided to take them to shore and showed them to a lot of people. They recognized the name Nehalennia, which was still readable on one of the stones. In the years after this discovery they excavated more of these votive stones, together with pieces of building materials. Suggesting that here too, once a Temple dedicated to the Sea Goddess stood.
