An exhibition about the work of Rafael Guastavino, who is known for the vaulted ceilings he created in landmark buildings like the Boston Public Library, Ellis Island’s Registry Hall and the Grand Central Terminal in New York, N.Y., opens March 26 at the Museum of the City of New York. “Palaces for the People: Guastavino and America’s Great Public Spaces,” an exhibition by Professor John Ochsendorf, was first shown at Boston’s Public Library last year, then traveled to the National Building Museum in Washington, D.C., and now opens March 26 at the Museum of the City of New York. The exhibition will be augmented with an array of related events in New York City, including an April 5 walking tour of Midtown, an April 12 tour of old City Hall Station and the Transit Museum, a May 3 tour of uptown and the Bronx, and several panel discussions and presentations.
