5. There’s a Safe Deposit Vault in the Basement

Safety Deposit Woolworth Building
The bank vault at The Woolworth is unique for its double door system

Irving National Bank was the Woolworth Building’s main anchor tenant until relocating to their new headquarters at 1 Wall Street in 1931 (they also changed their name to Irving Trust Company at that time). The bank vault is no longer in use, but still packed to the gills with safety deposit boxes and files.
