[4] In 2019, archaeologists from NIKU, using large-scale high-resolution georadar technology, determined that a 17-meter-long Viking ship was buried beside Edøy Church on the island of Edøya.
[12] Originally interred beneath a burial mound, in the present day the ship lies 50 centimetres below the topsoil due to years of plowing.
[13] Due to extensive fungus damage to the hull caused by field drainage, drought and exposure to the air, archaeologists called for an immediate dig to save the ship.
[14] Excavation of the ship at Gjellestad began in June 2020,[15] overseen by Professor Knut Paasche from the Norwegian Institute for Cultural Heritage Research.
Objects of particular interest included a large amber bead, a spindle whorl, a bracelet, horse and cattle bones, human remains, a comb, a whetstone, fragments of a wooden chest, and two Viking axe heads.
[25] The Viken and Halden municipalities intend to open a visitor centre at Gjellestad for viewing the outline of the ship.
