9. There’s A Water Tank in the Basement!

water tank in the Woolworth Building

The Woolworth Building was built atop a swamp, so this cedar water tank was added to the basement’s engine room in the 1970s to siphon out water that seeps up into the basement floor. It wasn’t used for long because the minerals from the water basically ate through the pipes. The water tank just sits pretty these days, in good shape protected from exterior elements.
