The scariest building: the mystery of skyscraper, which has no windows at all (3 photos + 1 video)
The building is designed as one of the most secure in the world. According to open sources, it has a supply of water, fuel and electricity, allowing autonomous operation for two weeks. 
In the heart of Manhattan (New York, USA), on 33 Thomas Street, there is a mysterious skyscraper that has raised questions among city residents and Internet users for decades. Unlike most high-rise buildings, this one is completely windowless, which has given rise to a lot of rumors and conspiracy theories.
The famous actor Tom Hanks even asked about the purpose of the building. In 2017, he tweeted a photo of the skyscraper with the caption: "This is the scariest building I've ever seen! What's going on inside?" 
TikTok user Eric Guidry (@e.guidry) clarified that the building is part of AT&T's communications infrastructure network. Before the digital age, such structures were used as key telephone hubs, where calls were physically switched between subscribers.
It turns out that these buildings housed powerful telephone switches and other telecommunications equipment that did not require natural light. To simplify the design and improve safety, windows were simply not added.
However, 33 Thomas Street stands out even among similar objects. The building is designed as one of the most secure in the world. According to open sources, it has a supply of water, fuel and electricity, allowing autonomous operation for two weeks. It is also assumed that the structure is capable of withstanding a nuclear explosion - within reason.
Conspiracy Theories
Despite the official explanation, there are many rumors surrounding the building. In 2016, the non-profit publication The Intercept published the results of an investigation based on documents from NSA whistleblower Edward Snowden. According to these data, 33 Thomas Street is allegedly used by the US National Security Agency (NSA) as a secret surveillance center under the code name TITANPOINTE.
A former AT&T engineer says the building houses a "massive gateway switch" that handles international calls and Internet traffic, suggesting that the building plays a key role in U.S. global surveillance programs.
While the building's documentary evidence of the NSA's connection remains controversial, the fact remains that 33 Thomas Street is a strategically important communications facility, and its functions may extend far beyond traditional telephony.
Conspiracy theorists continue to fantasize, calling the building a secret government base, a "vampire lair," or an alien lizard headquarters.
