World’s Largest Cog Found off Copenhagen
Named Svælget 2 after the shipping channel just outside Copenhagen where it was found, the ship dates to the early 15th century and offers rare insight into the scale, ambition, and technical sophistication of northern European seafaring during the Middle Ages.
The wreck was located in 2021 during excavations related to Lynetteholm, an artificial peninsula currently under construction at the entrance to Copenhagen Harbour, Denmark, which will become a new urban district and act as a storm surge barrier.
