The Story Of New York's Sidewalk Clock

In lower Manhattan, blocks from where the World Trade Center once stood, embedded deep into the sidewalk, is a clock. It's a simple clock, the hours and minutes are neatly displayed by spade hands, while roman numerals and train track minutes markers circle the dial.

All of this is cloudy, but visible under the scratched and stained crystal that occupies a break in the pavement at the intersection of Maiden Lane and Broadway. And it has been ticking away there, under the feet of Manhattan, for over a century.
