Rotterdam

Rotterdam is the Netherlands turned inside out: flattened by a 1940 bombing raid and rebuilt with nerve, it wears its architecture like a manifesto rather than a museum. Where Amsterdam curates the past, Rotterdam keeps building, and the result is a skyline of cantilevers, cube houses and the swan-necked Erasmus Bridge straddling Europe's busiest port. Approach it as a walking and cycling city, but budget time for the water too, since the Maas defines everything and a cheap harbour ferry doubles as a sightseeing cruise. The centre is compact enough to cross on foot in half an hour, yet the real texture lives in the neighbourhoods: multicultural Kop van Zuid, the leafy Kralingen lakes, the bar-lined Witte de Withstraat. Eat broadly, since this is the most diverse city in the country, with Cape Verdean, Surinamese, Indonesian and Turkish tables alongside sharp New Dutch cooking. Museums cluster conveniently around the Museumpark, markets thrum under the vaulted Markthal, and everything runs on an efficient metro. Come hungry, look up often, and let the city's restless energy set your pace.
