The architecture of the neighborhood includes apartment buildings along Park Avenue and Fifth Avenue, brownstones (with stoops) and townhouses on the side streets, condos, co-ops and a handful of mansions, of which some are now used by the Cooper Hewitt, Smithsonian Design Museum, The Jewish Museum, the National Academy of Design, the Dalton School and other organizations. From the 1950s to 1991, the National Audubon Society was housed in the Willard Straight House, a red brick Colonial Revival townhouse at 1130 Fifth Avenue. When it moved to NoHo, the International Center of Photography moved in but later consolidated its operations in Midtown near Bryant Park. In 2001, it again became a private residence. In 1989, the Jewish Museum demolished the 1963 modernist addition and courtyard, replacing it with a new extension opened in 1993 that mimics the French Gothic details of the Warburg Mansion, the museum's home since 1947. The limestone was crafted in Morningside Heights at the Cathedral Stoneworks. Frank Lloyd Wright's originally maligned and now celebrated Guggenheim Museum opened on Fifth Avenue in 1959. The New York Road Runners occupies a townhouse around the corner at 9 East 89th Street, a block informally known as Fred Lebow Place.
