Gdansk, Polandia
One of the prettiest cities in Poland, Gdansk, located in the Baltic Sea has played an important role in history, especially in the 20th century. The city was recorded in the critical times of World War II in 1939, then became the site of the movement of Solidarnosc workers in 1980, which began the end of Communist domination in Eastern Europe. The area of Tua Gdansk is a must-visit destination. The city is rebuilt with great care to restore the success of the previous Hansa League after being destroyed in World War II. The 14th-century City Hall is used as the city's historical museum.
