Discover the stunning and often hidden architecture of New York City’s most under appreciated engineers on our brand new tour : Guastavino’s New York. The Guastavino father and son team incorporated their tile arch system into dozens of buildings across the five boroughs including New York City’s most iconic landmarks like Grand Central Terminal, City Hall Station, and the Queensboro Bridge.

Travel up the east side of Manhattan to uncover these often hidden-in-plain-sight gems and learn what made Guastavino’s work so visually and structurally breathtaking while appreciating them firsthand. Among the highlights: Uncover one of Guastavino’s lesser known but most impressive vaults in lower Manhattan, look in on a space once known as “the Cathedral” built into a bridge, walk through the only Guastavino vehicular tunnel, and discover a hidden Guastavino vault in Grand Central Terminal (no it’s not the Whispering Gallery or the Oyster Bar). (Please note that this tour will not enter City Hall Station but guests will view it from the subway).

This new tour of created and led by Untapped New York’s Chief Experience Officer, Justin Rivers, and will launch in March with tour dates on March 10, March 28, April 10 and April 19.
