There are more than 8.5 million people living in New York and the city gets more than 60 million visitors every year. With so many eyes on it and so many cameras clicking away every minute of the day, you'd think there would be nothing left to uncover. But Manhattan still holds delicious secrets that many tourists – and even a lot of locals – don't know about.  Article by Traveller.
 

​This checklist of New York curiosities and hidden treasures – and the stories behind them – will make you an instant Big Apple know-it-all.

6½ AVENUE

"I worked just a few blocks from there for years and I never knew that existed!" said an American friend of mine when she saw my photos of 6½ Avenue. Tucked between 6th and 7th Avenue is the only New York street with a fraction in it. It's actually a series of connected walkways that threads through colonnades, arcades and atriums, so you can stroll six midtown blocks between 51st and 57th Streets without having to negotiate a traffic light, a crowded footpath or New York traffic.

WHERE? Between 6th and 7th Avenue and running between W51st and W57th Street

THE BERLIN WALL

There's more than a little irony that a symbol of communism sits inside the lobby of a building at the heart of Manhattan commerce. The slab of concrete, which is six metres long and almost three metres high, is a section of the Berlin Wall. The side that faced East Berlin has been kept intact, complete with bullet holes, a sobering reminder of what happened to those who tried to cross the boundary. The other side features a mural by German artists Thierry Noir and Kiddy Citny.

WHERE? Jefferies Building, 520 Madison Avenue, in the 53rd Street lobby between Madison and Fifth Avenues.


THAT SUBWAY GRATE

It's probably the most famous subway grate in the world. At one o'clock in the morning on September 15, 1954, while filming The Seven Year Itch, Marilyn Monroe stepped onto the grate as an uptown 6 train rushed by underneath. Her white halter neck dress blew up, exposing her legs as the train passed and an iconic image was born.

WHERE? Lexington Avenue near E52nd Street, southwest corner.
