20. The Riverside Park Engagement Ring

Until May 2014, a huge, fiberglass and wood engagement ring sat in Riverside Park South along the Hudson River near 66th Street as part of the annual Art Students League public sculpture program, Model to Monument (M2M). Reina Kubota created this art installation, titled “Ringo.” Atop the ring sat a “Big Apple” with a huge bite taken out of it. Naturally, Ringo became a popular spot for real marriage proposals.
