When the monumental and much-loved Pennsylvania Station was demolished in 1965 in the name of "progress," New Yorkers were shocked into action. The Landmarks Law was passed, offering a powerful means for protecting the city's prized structures, and this exhibit catalog from the Museum of the City of New York celebrates those efforts of the past 50 years—the failures as well as the triumphs. From the Astor Library to Grand Central Terminal, and whole districts like Greenwich Village, the book is an illustrated roll call of the places that we could not imagine New York City without.
