Formerly known by its German name Danzig, this city has survived six changes in power between Poland and its western neighbor since the 10th century. In the 13th century, Gdansk became an important Baltic port when it joined the Hanseatic League. Today the city near the mouth of the Vistula River is still a major commercial center and the headquarters of a prominent shipbuilding industry. It is also part of the sprawling 'Tri-cities' urban conglomeration of Gdansk-Gdynia-Sopot along the Baltic Sea coast, combining cultural, historical and resort attractions. Without doubt, the main attraction is the historic Old City. Virtually destroyed during World War II, the beautifully restored center draws thousands of tourists each year. More recent history marks Gdansk as the home of Solidarity and the beginning of democracy in Poland. Special Note: Tourism is still developing in Poland; guides, while the best available, may not be up to Seabourn's normally high standards.
