Yale is noted for its largely Collegiate Gothic campus as well as for several iconic modern buildings commonly discussed in architectural history survey courses: Louis Kahn's Yale Art Gallery and Center for British Art, Eero Saarinen's Ingalls Rink and Ezra Stiles and Morse Colleges, and Paul Rudolph's Art & Architecture Building. Yale also owns and has restored many noteworthy 19th-century mansions along Hillhouse Avenue, which was considered the most beautiful street in America by Charles Dickens when he visited the United States in the 1840s. In 2011, Travel+Leisure listed the Yale campus as one of the most beautiful in the United States.
