Archaeologists studying a farmer's field southeast of Oslo, Norway, have come across the rare remains of a buried Viking ship. The vessel, likely part of an elaborate burial ceremony for a high-ranking member of Viking society, was located using noninvasive ground-penetrating radar. In addition, the team also detected evidence of eight burial mounds and the remains of five longhouses dating back to the Iron Age.

According to archaeologist Lars Gustavsen, project leader from the Norwegian Institute for Cultural Research, the ship burial is only part of an ancient cemetery plot "which is clearly designed to display power and influence.”

According to the research team, the Viking vessel was likely once buried under a large mound that was steadily worn down by erosion and centuries of ploughing. Remarkably, they say the 66-foot-long ship today lies just below the topsoil at a depth of less than 20 inches. They're also fairly certain, at least based on the radar imagery, that the ship’s keel and floor timbers remain intact.

"We are certain that there is a ship there, but how much is preserved is hard to say before further investigation”, Morten Hanisch, county conservator in Østfold, said in a statement.

Interestingly, the site of the discovery sits directly next to the recently-excavated Jell Mound, which dates back around 1,500 years. According to the Smithsonian, archaeologists had previously assumed that any discoveries left to make around the site had been destroyed by farming practices. County officials told them to have a look anyways and the rest, as they happily found, is history.

For now, there are no plans to dig at the site. Instead, the team will continue using ground-penetrating radar to peel back time and see what other secrets this rare Viking find might be hiding.

"This find is incredibly exciting as we only know three well-preserved Viking ship finds in Norway excavated long time ago," said Dr. Knut Paasche, head of the Department of Digital Archaeology at NIKU. "This new ship will certainly be of great historical significance as it can be investigated with all modern means of archaeology."
