Gdynia is the youngest of the the Tri-City cities. It lies on the Bay of Gdańsk and it is above all, a city of great industrial and commercial significance with an important sea port. The main attractions are concentrated around located by the sea Kościuszko Square. There is, among others, the largest Sea Aquarium in Poland, and the ship-museums - Błyskawica (Lightning) and Dar Pomorza (Gift of Pomerania).
Until the interwar period, Gdynia was a small fishing village. After the First World War, when Poland was cut off from the port in Gdańsk, it was decided that the new port will be built here. Due to its history, there are no old monuments in the city, but many interesting examples of architecture from the interwar period can be found here. They include, among others, the modernist building of Polish Ocean Lines and built in the so-called academic style Bank of Poland.
For tourists, Gdynia is known primarily from the Marine Aquarium. The building is located by the sea and inside you can see several dozen pools with fish and sea creatures from various seas of the world. There are also colorful species of tropical fish that attract the attention of visitors.
Two ship-museums moor at the quay near the Akwarium. The first is ORP Błyskawica (Lightning), a destroyer built just before the Second World War, the second one is Dar Pomorza (Gift of Pomerania), a sailing ship that in the past served as a training frigate for the Maritime School in Gdynia. In the vicinity of the port there is also the Emigration Museum, opened in 2015 in the building of the former Sea Station. It presents the history of Polish emigration to different continents, using documents, photos and relations of emigrants.
