Medieval ship raised from Dutch riverbed

Archaeologists have raised a medieval ship from a riverbed in The Netherlands, where it had rested for more than 500 years.

The 15th-century "cog" was a trading vessel, used to sail the North and Baltic Seas.

Construction workers stumbled upon it when they were preparing to excavate the port in the city of Kampen.

Measuring 20 metres by eight, it had been buried beneath sand and silt.

Experts say its metal joints make it sturdier than other vessels of the same era, meaning they were able to raise it without it falling apart. They say it is rare to find such a well-preserved example.

Its features include a brick-arched oven and glazed tiles on the rear deck. It has been called "Ijsselkogge" after the river delta it was found in.

It emerged from the water in a specially constructed metal frame, with the straps around it controlled by a computer.

Archaeologist Wouter Waldus said that after they weighed the 40-tonne ship, they knew the structure was stable, enabling them to continue the operation.

The delicate vessel will be restored at the Nieuw Land Heritage Centre in Lelystad, where it will be kept wet at all times.
