6. 90 West Street Building
This 23-story Gothic Revival building was built in 1907 and designed by Cass Gilbert and the structural engineer, Gunvald Aus for the West Street Improvement Corporation. Originally built as an office building, the 90 West Street Building has gone through several names including the West Street Building, the Coal and Iron Exchange, and the Railroad and Iron Exchange.
The building was declared an landmark in 1998 and won a National Preservation Honor Award in 2006 from the National Trust for Historic Preservation. The South Tower of the World Trade Center was only 300 feet away from the 90 West Street building and as a result, it was severely damaged during 9/11. The building managed to survive the falling debris and the fires that went on for days which left the inside gutted and restoration began shortly after.
