(CNN)Here's what you need to know about the Empire State Building.
It stands 103 stories tall (1,250 feet to top floor, excludes height of antennae, which is 204 feet).
It is located on Fifth Avenue between 33rd and 34th Streets in Manhattan.
The Empire State Building 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. They attract around four million visitors annually.
Couples can sometimes see sparks when they kiss due to the static electricity at the top of the building.
The building has been featured in several movies such as "An Affair to Remember," "Sleepless in Seattle," "Elf" and "The Amazing Spider-Man."
Visitors can see 80 miles into New York, New Jersey, Connecticut, Pennsylvania and Massachusetts on a clear day.
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 (their anniversary) 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).
