The Polish Maritime Museum (Oddział Centralnego Muzeum Morskiego) is represented in Gdynia by the Dar Pomorza (Gift of Pomerania), a frigate dating back to 1909. The ship originally served as a training ship, and is now open to the public. Tours through the ship show visitors the twin decks, the engine room, sail store, officer's rooms, as well as the deck, the galley and the forecastle. The Dar Pomorze is also a frequent visitor to international tall ship shows.
