HANOVER, N.H. (AP) -- Murals by José Clemente Orozco at Dartmouth College have been designated as a new national historic landmark.
The Epic of American Civilization Murals are among 13 new national historic landmarks announced on Monday.
The National Parks Service says the murals are the most important work in the United States by Orozco, one of Mexico's foremost mural artists of the early 20th century.
The other 12 new national historical landmarks include an Alabama bridge that was the site of "Bloody Sunday" during the civil rights movement and the home of author and abolitionist Harriet Beecher Stowe in Hartford, Conn.
The National Parks Service says they are nationally significant historic places that possess exceptional value or quality in illustrating or interpreting the heritage of the United States.
