Sign of Light


Robert Wilson, artist; Richard Gluckman, architect


Commissioning Entity Pittsburgh Cultural Trust

Artist and theater director Robert Wilson and architect Richard Gluckman were commissioned by the Pittsburgh Cultural Trust to create artworks that used light to define the borders of the Cultural District. 

Sign of Light sits atop the old Joseph Horne building, now Penn Avenue Place. It looks like a blank billboard during the day. At night, however, more than 10,000 LEDs form a luminous triangle that rotates and changes colors. The sign is covered with a layer of vinyl to soften the light. The triangle is a reference to Pittsburgh's "Golden Triangle," the triangle of land that is created by the confluence of the Allegheny, Monongahela, and Ohio Rivers. 

Robert Wilson (b. 1941) is a renowned director in the theater world as well as an artist working with furniture design, drawing, and in sculpture. He spends a portion of the year at the Watermill Center in New York, which is a creative think tank for artists.
