A new exhibition at New York‘s Queens Museum will look at the city that could have been, with some of the boldest and strangest architectural ideas ever dreamt up for NYC all in one room. Titled Never Built New York, the exhibition features everything from Frank Lloyd-Wright’s idea for a “dream city” on Ellis Island to a 1925 plan to build skyscrapers underneath the city’s bridges. Some of the other never-realised architectural proposals include a floating airport and a dome over Manhattan that would regulate weather and reduce air pollution.

As well as images and models from 150 years of scrapped architecture, the exhibition is also set to feature a range of virtual reality installations — allowing visitors to take a tour of New York landmarks that almost looked very different. Never Built New York is open now, and will run at Queens Museum until February 18.
