One of Poland’s most beautiful cities, Gdansk, on the Baltic Sea, has played major roles in history, especially in the 20th-century.

Gdansk’s Old Town, painstakingly reconstructed to its Hanseatic League glory after being leveled in World War II, is a highlight. The 14th-century Town Hall houses the city’s historical museum.

Several sports teams and stadiums also call the city home, and its many museums outline the history of the region.
