Sopot and Gdynia are the duo that makes up the other two cities of the Tri-City area. Neither can outmatch Gdansk's historical sites, but each has its own distinct appeal.
While Sopot has obvious appeal, Gdynia, the most northerly of the Tri-City set, is an acquired taste and often skipped by tourists. You, too, could do the same unless you have time to spare. It is a concrete mass that started life as a quiet fishing village. In the early 20th century, the Treaty of Versailles created the Free City of Gdansk and thrust Gdynia into the newly reformed Polish State. It became Poland's access point to the sea and, in May 1921, the development started to convert it into a modern port. Today, it is a port city with all the trappings of a seaside town.
