Abandoned - 1 Seaport (New York's Leaning Tower)

Rising 60 stories along the East River of Manhattan, 1 Seaport at 161 Maiden Lane, was a luxury condo tower poised to become another iconic real estate venture in the city. However, after major construction mistakes were made, the tower and its owners entered a deep hole of financial turmoil, litigation and failed promises. All of this has left a once $400 million condo tower, completely abandoned in one of the densest cities on earth, now tilting precariously to one side. This is New York's leaning, abandoned condo tower.
