7. Kingsbridge Armory

The Kingsbridge Armory on Kingsbridge Road in the Bronx was been vacant since 1995. The 575,000 square foot building, once used to house the National Guard’s Eighth Coastal Artillery Regiment, has not been used for military purposes in more than 20 years. It has, however, been used for several other purposes, including the filming of the 2006 Will Smith film, I Am Legend.

In 2013, Mayor Michael Bloomberg and the New York City Economic Development Corp. unveiled an initiative to transform the Kingsbridge Armory in the Bronx into the world’s largest indoor ice facility. The plan, to be called the Kingsbridge National Ice Center (KNIC), will include 9 regulation ice rinks spread across multiple floors of the building. The $275 million project has had trouble getting financed within the last few years, though Mayor De Blasio this year offered assistance to get the project off the ground.
