Built by world-renowned architect Eero Saarinen, the TWA Flight Center opened in 1962, ushering in a new era of jet air travel. After TWA ceased operating, the terminal was closed in 2001 and has remained dark for the last 15 years. The terminal was designated a NYC Landmark in 1994 and listed on the National Register of Historic Places and the New York State Register of Historic Places in 2005. (TWA Hotel)
