25 times a year

Its tall, elegant steel structure is definitely captivating; no wonder thousands of photographers, painters, and filmmakers have chosen the Empire State Building as the backdrop for their work. However, that imposing height comes with something a little scary: it's estimated that the building is struck by lightning about 25 times a year! Fortunately, it was designed to handle these strikes, so it's completely safe.

Really fast

There are buildings that took decades to complete. But this is not the case with the Empire State Building. In fact, this is one of the fastest skyscrapers ever built: It took only one year and 45 days to erect such an architectural masterpiece. That means it was built at a rate of an incredible 4.5 floors per week!

Unlikely survivor

It was 1945 when the Empire State Building was accidentally struck by a B-25 Mitchell bomber due to the thick fog that covered NYC. A worker named Betty Lou Oliver was on the 80th floor when the plane crashed into the 79th. She was severely injured, but incredibly, she survived. Hours later, while being rescued in an elevator, the damaged cables gave way, and Betty fell 75 floors to the basement. She survived that too!

40 million dollars

A tremendous building like the Empire State couldn't be built on a shoestring budget. When it was constructed —in the midst of the Great Depression, no less— it cost about $41 million. That's a hefty sum, even today! Adjusted for inflation, that would be around $600 to $700 million in 2025. Wow!

Secret floor

If you are afraid of heights, be prepared: the Empire State Building has two public observation decks, one on the 86th floor and another on the 102nd. But there's another one, and it's even higher! It's located on the 103rd floor, but it's not open to the public and is mostly used for VIPs or special occasions.

High security

Although an incredible 4 million people visit the building each year on average, getting in isn't easy. Many visitors say it feels like going through airport security, with X-ray machines and metal detectors everywhere. Visitors must also pass through a security checkpoint before reaching the observation decks, and the building is constantly monitored by cameras and security guards.

King Kong

We all remember the iconic scene of the imposing King Kong climbing the towering mast of the Empire State Building. And while that image lives on in our minds, there's one detail many people overlook: When the original King Kong movie premiered in 1933, the Empire State Building was less than two years old! Plus, at the time, the building still held the title of tallest in the world, making King Kong's climb even more epic.

Underground waterways

Beneath what is now NYC, there was a network of streams and rivers that flowed freely before Manhattan and other boroughs covered them. The land below the Empire State Building is no exception, and these old underground waterways still occasionally cause complications. For example, during heavy rains, water can rise and seep into the building's wind tunnels, sometimes flooding areas with up to two feet of water.

The original plans

The Empire State Building was originally supposed to have a dirigible anchor! That's right; the mast at the top of the building was meant to serve as a mooring post for dirigibles, with a docking platform and a door for passengers to disembark. However, due to the extreme height, high winds, and overall potential danger, the idea was discarded. Today, the mast is used for antennas and other communications equipment.

Green building

This iconic building that defines New York's skyline is considered a "green building." And no, it has nothing to do with the color of its walls; it's about something much more meaningful. The sustainability modifications that the Empire State has undergone over the years have made it one of the most energy-efficient buildings of its size, minimizing its environmental impact and earning it the title of "green building."
