#5. Rotterdam Netherlands
Rotterdam is a major port city in the Netherlands’ province of South Holland. The Maritime Museum’s vintage ships and exhibits trace the city’s seafaring history. The 17th-century Delfshaven neighborhood is home to canalside shopping and the Pilgrim Fathers Church, where pilgrims worshiped before sailing to America. After being almost completely reconstructed following WWII, the city is now known for its bold, modern architecture.
