A new Dale Chihuly sculpture was unveiled this morning in Union Square Park. The artist, famous for his colorful glass sculptures and elaborate chandeliers—many of which currently adorn upscale casinos, glitzy hotel lobbies, and yachts—was on hand for the unveiling, along with NYC Parks Manhattan Borough commissioner William Castro, and others.

The 31-feet tall sculpture, called Rose Crystal Tower, is part of the NYC Parks' program Art in the Parks, which is celebrating its 50th anniversary this year. Art in the Parks is responsible for many notable works of art in public green spaces around the city, including the OY/YO installation in Brooklyn Bridge Park. Past installations have included works from the likes of Robert Indiana, who first displayed his famous Love sculpture at the entrance of Central Park in 1971.

The Rose Crystal Tower is composed of Polyvitro crystals and steel. According to the announcement from the Parks Department, Polyvitro is "the artist’s term for a plastic material which he casts into individual chunks which resemble glass, but are lighter and more resilient."

Chihuly's sculpture is located on the east side of Union Square Park, at 15th Street and Park Avenue South. The work will be on display through October 2018.
