The Rothko Chapel is an interfaith sanctuary, a center for human rights — and a one-man art museum devoted to 14 monumental paintings by abstract expressionist Mark Rothko. The Houston landmark, commissioned by John and Dominique de Menil, opened its doors over 40 years ago, in February 1971.

For the past four decades, the chapel has encouraged cooperation between people of all faiths — or of no faith at all. While the chapel itself has become an art landmark and a center for human-rights action.

Rothko committed suicide a year before its opening.
