Manhattan's Loveliest 'Ghost': the abandoned 1904 City Hall subway station

Even in a city as densely populated and widely photographed and palimpsestically overwritten as Manhattan, there remain places of breathtaking beauty that are almost unknown. Take, for example, the 1904 City Hall subway station, a closed 'ghost station' since 1945. It is the work of master builder Rafael Guastavino, now the subject of an exhibition at the Museum of the City of New York. Martin Filler has written a beautifully illustrated article about the exhibition on the New York Review blog.
