Considering it was bombarded 146 times during World War II, you might think there’d be little left to see in Le Havre—France's second-largest port (after Marseille). Think again. The rebuilt city, with its uncompromising recourse to reinforced concrete and open spaces, is admittedly short on old-school charm; on the flip side, it is home to some of France's most spectacular 20th-century edifices. The rational planning
and audacious architecture of Auguste Perret (1874–1954) have now earned the city UNESCO World Heritage status. His unforgettable Église St-Joseph—half rocket ship, half church—is alone worth the trip.
