The Gdynia City Museum, established in 1983, is a municipal cultural institution that documents the history of Gdynia. Its origins date back to 1968, when the City History Documentation Department was initiated at the Municipal Public Library. The museum is housed in a building known as Abraham's House at 30 Starowiejska Street, while its exhibition activities took place in the Exhibition Pavilion at 21 Waszyngtona Street. In 2007, the museum opened a modern building at Zawiszy Czarnego Street, significantly enhancing the quality of its presentations and adapting the space to new architectural challenges and social needs. The museum documents the city's history, particularly the interwar period of the Second Polish Republic, and promotes aspects of Gdynia's modernity, including design, architecture, and art. Its collections exceed 63,000 items, including documents, paintings, and objects of material culture, as well as over 11,000 volumes in its scholarly library. The museum also runs the "Gdynia Online" Digital Archive, which enables the digitization of collections and makes them accessible to a wide audience. In 2022, it won the Sybilla Award for the "Year of Tadeusz Wenda in Gdyni" project. The museum comprises various departments, including the Historical Department, the Art Department, and the Education Center. Over its thirty-year history, the museum has undergone significant evolution, reflected in both its architecture and collections. Notable individuals who have directed the museum include Wojciech Zieliński, Stefania Lemańska, Dagmara Płaza-Opacka, Jacek Friedrich, and the current director, Karin Moder. The museum is a valuable institution for the culture, education, and history of Gdynia, and its activities highlight the city's close relationship with the sea and its dynamic development.
