The stars, bars, bubbles, and petals of Manhattan manhole covers

Underfoot all over New York City are late 19th and early 20th century manhole covers embossed with unusual shapes and designs. There’s a practical purpose for this: raised detailing helped prevent people from slipping (and horses from skidding) as they traversed Gotham’s streets in wet weather.

They’re also a form of branding. The city’s many foundries of the era manufactured manhole and coal hole covers. Each foundry company seemed to have chosen a specific design or look to represent them.

And let’s not leave out the artistry that went into these. Manhole covers aren’t typically thought of as works of art, but there’s creativity and imagination in the different designs we walk over and tend not to notice.

J.B. and J.M. Cornell, who operated an ironworks foundry at 26th Street and 11th Avenue, added bubble-like details and smaller dots to their covers, as seen on the example (at top) found in the East 70s near Central Park. They also added swirly motifs on the sides, prettying up these iron lids and making the name and address easier to read.

McDougall and Potter, on the other hand, went for a classic star to decorate this cover on East 80th Street (second photo above). This foundry on West 55th Street also chose bars and dots, within which they included the company name and address.

This cover (above) on 23rd Street near Fifth Avenue, likely by Jacob Mark & Sons on Worth Street, once has colored glass embedded in that hexagram design. A century and then some of foot and vehicle traffic wore them down and pushed some out.

Could those be flower petals decorating the hexagram shape on this cover, also by the Mark foundry? Located near Broadway and Houston Street, it’s unique and charming, especially with the tiny stars dotting the lower end.

The mystery manhole cover on Central Park West

The most interesting manhole covers are the ones that tell us who made it and when it was put in place: the name of an ironworks company, the initials of a city department, a date.

This cover, on Central Park West south of 86th Street, doesn’t offer much in the way of clues.

The two decorative stars feel very 19th century. “Water Supply” could certainly mean it was part of the Croton Aqueduct system; its location outside Central Park could be evidence that it had something to do with the receiving reservoir that existed in the park.

It looks like no other manhole cover I’ve encountered in Manhattan. But there is an identical one in Brooklyn (above). It’s on Eastern Parkway near Prospect Park.
