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 serves as the display framework for a major work of modern art: on its walls are fourteen paintings by Mark Rothko in varying hues of black. The shape of the building—an octagon inscribed in a Greek cross—and the design of the chapel were largely influenced by the artist. The chapel sits 2 mi (3.2 km) southwest of downtown in the Montrose 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 110,000 people visit the chapel each year.
