The main buildings of the National Museum in Szczecin (Muzeum Narodowe w Szczecinie) is located at the Chrobry Embankment, in the former Maritime Museum. Here you will find thousands of historic artifacts from the region, information about the seafaring history of the city, as well as a new permanent exhibition on the Golden Age of the Pomeranian Region. Also worthwhile is a view from the viewing tower on top of the museum, although the climb to the platform via a narrow staircase is said to be challenging.
Also part of the National Museum is Szczecin's History Museum (Muzeum Historii Szczecina), which is situated in the Old Town Hall.
