The event marks the second anniversary of the ratification by Poland of the 2001 UNESCO Convention on the Protection of Underwater Cultural Heritage.
The exhibition features the latest findings of research on shipwrecks discovered in a submerged medieval harbour in Puck, northern Poland, as well as the achievements of Polish maritime archeology and the results of conservation efforts concerning artefacts from the maritime environment.
The show offers a cross-section of the five decades of research conducted by the National Maritime Museum in the Polish Baltic city of Gdańsk.
The director of the National Maritime Museum in Gdańsk, Robert Domżał, has told the media that the Convention on the Protection of Underwater Cultural Heritage specifies the measures that are recommended for the protection of all traces of underwater human activity and defines the ways and means of sharing information between signatory states.
He added that Poland "is duty-bound to present to UNESCO reports on the state of protection of underwater heritage," including shipwrecks and archeological sites.
The exhibition at the Salle des Actes of the UNESCO House in Paris runs until March 17.
