The urban post-war rebuild wasn’t exactly equal in the Netherlands. Take Rotterdam: rebuilt from ruins to provide Europe with its largest port. Today, it still does. Fittingly, the city was also saddled with the continent’s largest red-light district. Today, you can start there, in the once-dingy Katendrecht neighbourhood, to witness Rotterdam’s current ascent. It’s now the city’s culinary heart, with its Deliplein Square, an outdoor dining room ringed by restaurants and a waterfront warehouse packed with stalls, breweries and workshops. Rotterdam is also Europe’s design and architecture lab. Places like nearby Wilhelminakade, the steamship embarkation point for U.S.-bound Dutch émigrés, is today home to towers designed by Álvaro Siza, Norman Foster and local starchitect Rem Koolhaas. There’s even an all-timber floating office building moored nearby, along with Hofbogenpark, Rotterdam’s own High Line. On the other side of town, in the M4H district, a new floating farm blends urban food security with community amenities. What rising sea levels? Sustainable architecture elsewhere includes the air-filtering Smog Free Tower and the Windwheel (you’ll have to see it to believe it). With that kind of office space, no wonder the city’s workers rank in the Top 10 for Labour Force Participation.
