Volunteers dedicated a new sculpture, "Lunar Horizon," in Project GREEN Gardens, created by artist Nick Goergen.
The 8-foot patinated steel moon gate symbolizes a passage between the natural and spiritual worlds. Traditional in Chinese and Japanese architecture, moon gates create a circular opening between terrestrial and celestial realms.
"The moon gate, measuring eight feet in diameter, forms a perfect circle to frame nature, the gardens, and the historic Ashton House," Goergen said. Positioned between the gardens and the Iowa River Trail, the sculpture creates a visual connection from both directions. Looking through the gate from the gardens frames the trail and surrounding landscape, while the view from the trail highlights both the gardens and the historic mid-century Ashton House.
The limestone that accents and anchors the sculpture matches the Ashton House.
The dedication also marked the conclusion of Goergen's three years as a Project GREEN Gardens volunteer while pursuing graduate studies at the University of Iowa. The Arizona native earned his Master of Fine Arts degree this spring after receiving his M.A. in Art in 2025. During his time at the university, he also taught metal sculpture.
After fabricating and welding the sculpture in the university's art studios, Goergen and three student colleagues installed it on a concrete foundation set one foot into the ground. A protective metal sealer was applied, and the finished patina complements the bird blind installed earlier this spring.
Throughout his volunteer service, Goergen quietly integrated his artistic practice with the rhythms of the natural landscape. Many of the plant materials he collected at Project GREEN Gardens became part of his MFA exhibition, "A Lived Naturism."
The installation was made possible through a $4,000 matching grant awarded to Project GREEN by the City of Iowa City.
As Nick Goergen begins the next chapter of his career in Oregon, he leaves behind more than a sculpture. He leaves a lasting reminder of the three years he spent volunteering in Project GREEN Gardens and of the connection between art, nature, and community. Lunar Horizon will continue to frame the gardens, the Iowa River Trail, and the memories created there for years to come.
