Alamo, also known as the Astor Place Cube or simply The Cube, is an outdoor sculpture by Tony Rosenthal, located on Astor Place, in the East Village neighborhood of Manhattan in New York City. It is a black cube, 8 feet (2.4 m) long on each side, mounted on a corner. The cube is made of Cor-Ten steel and weighs about 1,800 pounds (820 kg). The faces of the cube are not flat but have various indentations, protrusions, and ledges. The sculpture's name, Alamo, is designated on a small plaque on the base and was selected by the artist's wife because its scale and mass reminded her of the Alamo Mission. It was fabricated by Lippincott, Inc.
