(CNN) Here's a look at the Empire State Building.
Located on Fifth Avenue between 33rd and 34th streets in Manhattan.
It is 103 stories tall (1,250 feet to top floor, excluding height of antennae, which is 204 feet).
Took only one year and 45 days to build, or more than seven million man-hours.
There are observatories on both the 86th and 102nd floors.
The building has been featured in several movies such as "An Affair to Remember," "Sleepless in Seattle," "Elf" and "The Amazing Spider-Man."
From the observation decks, visitors can see as far as 80 miles away into New York, New Jersey, Connecticut, Pennsylvania and Massachusetts on a clear day. The distinctive binocular viewers around the building were made by Tower Optical company.
The tower lights are turned off on foggy nights during the spring and autumn bird migration seasons, so the lights will not confuse birds and cause them to fly into the building.
Every year on Valentine's Day, couples who marry on the 80th floor become members of the Empire State Building Wedding Club. They receive free admission to the observatory each year on February 14 thereafter.
Over thirty people have jumped to their deaths from the Empire State Building.
The Empire State Building Run-Up is an annual race up the stairs to the 86th floor (1,576 steps).
The building has 24/7 security. It is monitored with security technology, such as CCTV cameras, and the screening for visitors is similar to airport security procedures.
