Frank Lloyd Wright is one of architecture’s most important figures, and you can see his work in five countries and 37 of 50 states. But when it comes to New York City, there is only one major Wright construction to be found: The Guggenheim. There is also a pre-fab house in Staten Island and one in Blauvelt just north of the city, but what other work did he do in the five boroughs? It turns out that Wright designed two other major projects in NYC, but both have been demolished. Here’s a look at these lost works by the great architect.

Everyone knows Manhattan is all about high-rise condos, tall apartment buildings, and any other kind of building in which people live above other people. But it wasn’t always that way. A hundred years ago, there was still room on this small island for the ultra-rich to build mansions all to themselves, single-family homes with the square footage of a castle. Today many of these buildings, all “Millionaire’s Row” mansions in the Upper East Side, belong to museums and schools, but the question remains: What are the biggest buildings in Manhattan today that were built as single-family homes?

In New York, many of the grand Beaux-Arts masterpieces — Grand Central Terminal, the Queensboro Bridge, the City Hall subway station, Columbia University, and the Cathedral of St. John the Divine — have one striking element in common: Guastavino tiles. Spanish architect and builder Rafael Guastavino and his son Rafael Jr. brought with them to New York at the end of the 19th century a Mediterranean design technique from the 14th century for thin-tile structural vaulting. The expertly engineered and architecturally beautiful vaults were lightweight, fireproof, load-bearing, cost-efficient, and able to span large interior areas.

Today there are over 250 Guastavino works in New York City alone, not to mention the 1,000 throughout the U.S. The Museum of the City of New York’s current exhibition, Palaces for the People: Guastavino and the Art of Structural Tile, explores Guastavinos’s spaces in New York and showcases “never-before-seen objects, artifacts, photographs, and documents.” We couldn’t help doing a little Guastavino exploration ourselves, and have put together some of our favorite tiled sites that you can actually visit.
