NEW YORK — The Guggenheim Museum's spiral facade will be turned into a public art installation when it is illuminated in large-scale text to celebrate its newly restored exterior.

Mayor Michael Bloomberg is scheduled to flip a switch Monday night that will suffuse the Frank Lloyd Wright-designed building with "For the Guggenheim," a commissioned work by Jenny Holzer. The text contains the artist's own writings and numerous poems.

The museum was encased in scaffolding in 2005, when restoration began, to address surface cracks that have plagued the innovative concrete design almost from the day it opened in 1959. The work was completed in July and included removal of 11 coats of paint, filing in cracks, treating corroded steel structures and reinforcing the concrete.

The restoration was initiated by a gift from Peter B. Lewis, who served as chairman of the Guggenheim Board of Trustees from 1998 to 2005.

The building will be lighted every Friday, beginning this week through Dec. 31, from dusk to 11 p.m. There will be an additional showing on New Year's Eve.

Holzer is known for projects that draw on the power of the written word. Her projections have appeared around the world at such galleries and museums as Mies van der Rohe's Neue Nationalgalerie in Berlin and I.M. Pei's Pyramide du Louvre in Paris.

The Guggenheim has satellite sites in Venice, Italy, Berlin and Bilbao, Spain. In 2013, it is slated to open a Frank Gehry-designed museum in Abu Dhabi.
