TITANPOINTE. 

New York City has skyscrapers of all shapes and sizes. But why does this 500 foot tall, 29-story building have no windows, no lights and no markings at all?  Because it's a top-secret NSA spy station built to withstand nuclear war.  

Officially, this is an AT&T telecommunications building. But thanks to leaked documents, we now know that 33 Thomas Street is actually a top secret NSA mass surveillance hub.  It's code name is: TitanPointe. And right now, as we speak, TitanPointe is listening.  

The gray, granite tower is located at 33 Thomas Street in Lower Manhattan. Locals know the building as the "Long Lines Building" and it's been a source of mystery for years. What jumps out is that the building has no windows and no exterior lighting. During the day, it fades into the background of the New York City skyline. And at night, it becomes an invisible shadow.  

Thanks to NSA documents leaked by Edward Snowden, we now know that creating an invisible building wasn't an accident. It was absolutely by design.  

33 Thomas Street operates under NSA codename TITANPOINTE. And Titanpointe is a core location used for a controversial, and possibly illegal, NSA-sponsored mass surveillance program. According to leaked documents, this program has targeted the communications of the UN, the World Bank, the IMF. It's been used to spy on at least 38 countries, including US allies like France, Germany and Japan.  

It's common knowledge that AT&T is very cooperative with the NSA. Using an AT&T cell phone? Eh, you might want to rethink that.   

Let's find out why.
