The Metropolitan Opera House contains 3,800 seats and 195 standing room places and was designed by architect Wallace K. Harrison. Although west-east roads do not run through Lincoln Center itself, the Metropolitan Opera House is parallel to the block from West 63rd Street to West 64th Street. The rear of the House meets Amsterdam Avenue and the entrance to the Opera House is at Lincoln Center Plaza which begins at Columbus Avenue. The building is clad in white travertine and the east facade is graced with a distinctive series of five arches.
On display in the lobby, and visible to the outside plaza, are two murals created for the space by Marc Chagall. The murals are approximately 30 ft (9.1 m) by 36 ft (11 m). The south wall holds the work entitled The Triumph of Music while the north wall contains The Sources of Music. In 2009, the opera's board of directors decided to use the paintings as collateral for a long-term loan which previously relied on cash for backing. Some sources estimate the value of the paintings at $20 million.
