Gdynia   is a port city in northern Poland. Gdynia, together with nearby Gdańsk and Sopot are often referred as Tricity (pl: Trójmiasto). Gdynia was first mentioned in the 13th century as a fishing village. Its career began after World War I, when it became Poland's main harbour and the big sea port at the Baltic Sea, which it still is.
Gdynia is one of the youngest and most modern cities in Poland. In the early 1900s Gdynia was a little village, but after WW1 and the establishing of the Free City of Gdańsk, the Polish Government decided to build a deep-sea port. Construction began in 1921. The city rose fast in the 1920s and 1930s, so the architecture and planning reflect European trends of the day - Modernism. The city continues to grow to this day. Today, Gdynia is a modern city with a population of a quarter-million and is the second major Polish port on the Baltic Sea after Gdańsk.
