Though it flies under the radar as a major tourist destination, this prosperous, bustling port city on the Baltic is flush with Modernist architecture and a living maritime museum history. A small fishing village before the 20th century, Gdynia began its transformation into a key seaport in 1926. Today it sparkles with a unique “City of the Future” optimism. Climb aboard a pair of proudly preserved ships – the ORP Blyskawica (“Lightning”) destroyer and fully rigged frigate Dar Pomorza – for hands-on history before visiting museums dedicated to Poland’s emigrants, naval history, vintage cars and motorcycles and more. After a bite in cosmopolitan Kosciuszko Square, stroll the white sands of Gdynia Beach.
