Gdynia is a city in northern Poland and a seaport on the Baltic Sea coast. With a population of 243,918, it is the 12th-largest city in Poland and the second-largest in the Pomeranian Voivodeship after Gdańsk. Gdynia is part of a conurbation with the spa town of Sopot, the city of Gdańsk, and suburban communities, which together form a metropolitan area called the Tricity with around 750,000 inhabitants.
Historically and culturally part of Kashubia and Eastern Pomerania, Gdynia for centuries remained a small fishing village. By the 20th-century it attracted visitors as a seaside resort town. In 1926, Gdynia was granted city rights after which it enjoyed demographic and urban development, with a modernist cityscape. It became a major seaport city of Poland. In 1970, protests in and around Gdynia contributed to the rise of the Solidarity movement in nearby Gdańsk.
