Mount Washington Hotel - View this location on map This was the largest spa (352 rooms) in the White Mountains when it opened in 1902. Built in Spanish-Renaissance style, it is a large wooden frame, Y-shaped structure with two five-story octagonal towers. Its isolation and scale made it the choice location of the 1944 Bretton Woods Conference, an international gathering of economists, lawyers, and politicians to chart a blueprint for the world's monetary system. The World Bank was established at this Conference. New Hampshire Historical, Hotel
