230 Park Avenue awash in light. (Evan Joseph)

On Monday, December 3, the “Jewel of Park Avenue” at 230 Park, aka The Helmsley Building, really began to sparkle as building-owner Monday Properties unveiled a new LED lighting display to a crowd huddled at the base of the building, staring upward with anticipation as rush hour traffic swirled around. Monday Properties President and CEO Anthony Westreich and Manhattan Borough President Scott Stringer stood together to push a giant red button, officially triggering the light show, which flickered into action, turning heads of passers by for blocks around as a live violinist provided musical accompaniment.
