CHORUS is an expansive field of text-based artwork in marble mosaic created by Ann Hamilton for the rebuilt WTC Cortlandt station as part of the World Trade Center reconstruction, serving visitors to the 9/11 Memorial and Museum.

CHORUS spans a total of 4,350 square feet and is integrated into the architectural design of the new WTC Cortlandt station that replaced the station destroyed on September 11, 2001. The artwork features a woven field of raised-text taken from the U.S. Declaration of Independence and the 1948 United Nations Universal Declaration of Human Rights, which conveys a universal language and a timeless artistic excellence. This concordance of Rights and Declarations frames the station platforms, creating an immersive environment and inspiring public space to be experienced by riders and visitors.

The artwork was created as the result of close collaboration between Ann Hamilton, typographic designer Hans Cogne, and artisans at Mayer of Munich. Set in monochromatic marble stone, the woven text forms an underground refrain that speaks to the civic ideals and aspirations foundational to the quality of life above. The white-on-white tactile surface invites subway riders to touch the text as they read the words, creating meaningful personal encounters. These underground crossings of texts and people are the social, legal and institutional pillars that underlay cultural life above ground.

Ann Hamilton is internationally recognized for her large-scale mixed-media installations. Noted for a dense accumulation of materials, her works poetically respond to the architectural presence and social history of their sites. Hamilton is a MacArthur and a Guggenheim fellow. She won the Skowhegan Medal for Sculpture, and represented the United States in the 1991 Sao Paulo Bienal, and the 1999 Venice Biennale. In 2015, Hamilton was honored with The National Medal of Arts, the highest award given to artists by the US government.
