The Rothko Chapel is a non-denominationalchapel 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.
One of Morton Feldman's best known pieces of music was inspired by and written to be performed in the chapel — it too is called Rothko Chapel (1971).
