World's Most-Visited Tourist Attractions
No. 3 Union Station, Washington, D.C.
Annual Visitors: 37,000,000
Opened in 1907, this busy station shuttles some 12,500 passengers daily in and out of the city. But it also handles serious tourist traffic: 37 million who pass through to take in the impeccably mixed architectural styles throughout the colossal building: from Classical to Beaux-Arts to Baroque. More than 70 retail outlets make Union Station a shopping destination, and it’s also a jumping-off point for many D.C. tours. —Joshua Pramis
