Gdynia is a city in the Pomeranian Voivodeship on the Bay of Gdańsk. It is one of the three cities which belong to the famous "Tricity", visited by vast numbers of tourists every year. The rapid development of the city began in the 1920-ties, following the Polish government’s decision to build the country’s major seaport at Gdynia village. The village started to extend drastically as workers from all over the country came here to help build the port. In 1923 the first ship (the French ship Kentucky), entered the harbor. Within several years Gdynia developed from a small village to the most modern port town on the Baltic Sea.
