"The Bathtub" refers to the underground foundation area at the site of the World Trade Center and accompanying buildings in New York City. The term bathtub is a misnomer, as the area does not hold any water; rather the purpose of its design is to keep water out.
The Bathtub encompasses a large, roughly rectangular excavation down to bedrock surrounded by reinforced concrete walls, intended to serve as dams to prevent water intrusion from the nearby Hudson River (North River). The World Trade Center site was located on man-made water-clogged landfill that had accumulated over centuries, providing an extension of land out onto the Hudson River from the original Manhattan shoreline, with bedrock located 65 feet (20 m) below. Manually removing water from this area would have severely altered the water levels surrounding the World Trade Center site and thus jeopardize the foundations of nearby buildings, causing them to sink. This is why the Bathtub method was used.
The Bathtub contains a 16 acres (65,000 m2) site, including seven basement levels, the downtown terminal of the Port Authority Trans-Hudson rapid transit line, and the preexisting New York City Subway's IRT Broadway – Seventh Avenue Line (1 trains). The South Tower of the World Trade Center was actually built around the PATH tubes that passed through the foundation area, thus service was uninterrupted throughout the whole of the construction period. The waterproof walls are 3 feet (0.91 m) thick and 70 feet (21 m) high.
I'm with the coldest God watching the joys of mortals
I'm hidden in the fog, in fear that they'll hear my sorrows
I'm at the gates of dreams, although my hopes are empty
While my soul turns into frost...
The wasteland is my kingdom
All I hear is silence
There's just the desolation of a reign of bitterness and sorrow
I'm with the coldest God, watching the joys of mortals
I'm hidden in the fog, because it brings me comfort
I'm bound to my own grave
There is no one to pray for me
I chose to be alone
Fairies are removing the green circles from the forest
They know there is no place for them anymore
Fairies know they have to leave the forest
Where is my faith? Oh, my guardian angel...
