Archaeologists discovered six medieval ships at least 500 years old in April 2019 in the modern Bjørvika district in connection with urban refinement and the construction of a high-speed railway. The ships date back the 1300s-1600s. The project manager and archaeologist of the Norwegian Maritime Museum, Elling Utvik Wammer, noted that the findings are unique in Norway and called them “an archaeological fairytale”. The last ship found here in ten meters long is reportedly a cargo ship of the 16th century. Another archaeologist Marja-Liisa Grue supposes that it could be used to carry stones to nearby Akershus Fortress. The archaeologist team believe that the findings will light upon the great city fire of 1624 and the little-known period named Reformation in Norway history.
