Rothko Chapel  The Rothko Chapel is a non-denominational chapel in Houston, Texas, founded by John and Dominique de Menil. The interior serves not only as a chapel, but also as a major work of modern art. On its walls are fourteen black but color-hued paintings by Mark Rothko. The shape of the building, an octagon inscribed in a Greek cross, and the design of the chapel was largely influenced by the artist. The chapel sits two miles southwest of downtown in a suburban neighborhood situated between the building housing the Menil Collection and the Chapel of Saint Basil on the campus of the University of Saint Thomas. About 55,000 people visit the chapel each year. Susan J. Barnes states "The Rothko Chapel...became the world's first broadly ecumenical center, a holy place open to all religions and belonging to none. It became a center for international cultural, religious, and philosophical exchanges, for colloquia and performances. And it became a place of private prayer for individuals of all faiths"   On September 16, 2000, the Rothko Chapel was placed on the National Register of Historic Places. In 1964 Rothko was commissioned by John and Dominique de Menil (also founders of the nearby Menil Collection) to create a meditative space filled with his paintings. The works are site-specific, one of the requirements of the program. As Rothko was given creative license on the design of the structure, he clashed with the project's original architect, Philip Johnson over the plans for the chapel. The plans went through several revisions and architects. Rothko continued to work first with Howard Barnstone and then with Eugene Aubry, but ultimately he did not live to see the chapel's completion in 1971. After a long struggle with depression, Rothko died by suicide in his New York studio on February 25, 1970. From 1973 onward, the Rothko Chapel doubled as a center for colloquiums aimed at fostering mutual understanding on issues affecting justice and freedom throughout the world. The first colloquium drew scholars from Lebanon, Iran, India, Pakistan, Nigeria, Japan, Italy, the United States and Canada. In 1981, it initiated “The Rothko Chapel Awards to Commitment to Truth and Freedom." In 1986, a second award was established to honor and emulate the spirit of Óscar Romero, Archbishop of San Salvador, who was murdered on March 24, 1980. These Rothko Chapel Awards have recognized individuals and organizations who, at great risk, denounce violations of human rights.
