Architecture SPOTTED. Palaces for the People: Guastavino and the Art of Structural Tile | Museum of the City of New York. Exhibition exploring the innovations of the Guastavino Fireproof Construction Company (1889-1962) brought to the science and art of building. The system of structural tile vaults developed by the Guastavinos—lightweight, fireproof, low-maintenance, and capable of supporting significant loads—was used by leading architects of the day, including McKim, Mead & White and Carrere &Hastings. Ellis Island’s Registry Room, Carnegie Hall, the Bronx Zoo’s Elephant House, and Grand Central Terminal all contain Guastavino vaults. Organized by MIT’s John Ochsendorf, the exhibit includes some 20 key Guastavino spaces in the five boroughs.
