Walls That Speak: Honoring the Magic of Isaiah Zagar

As part of a new series about SCH's permanent art collection, Director of Arts Megan Monaghan writes about the late Isaiah Zagar's artwork in Thornley Middle School.

Few artists have shaped Philadelphia’s public art like Isaiah Zagar. His mosaics, bursting with vibrant tiles, recycled objects, mirrored fragments, and playful imagination, transform ordinary walls into joyful, immersive experiences. From South Street to the hallways of SCH, his mosaic work invites viewers to slow down, look closely, and discover meaning in every detail. 

Zagar’s visionary creativity transforms SCH’s hallways, where his mosaics in the Permanent Art Collection fill the Thornley Middle School Building with bold imagination and the spirit of shared creation. His work exemplifies SCH’s Walls That Speak series—telling a story, embodying a vision, and carrying forward Zagar’s legacy as an artist to inspire generations.

Zagar brought his artistry to SCH in 2006 through the Springside 1957 Artist in Residence Fund. Middle School girls helped create tiles and assisted in the installation of multiple mosaic works. Their collaboration reflects the heart of Zagar’s practice, rooted in community, shared creation, and the belief that art belongs to everyone.

Among Zagar’s most iconic works is Philadelphia’s Magic Gardens, the immersive South Street installation he began in 1994 by reclaiming vacant lots and transforming them into a three-dimensional mosaic environment filled with poetry, portraits, and unexpected materials such as bottles and bicycle wheels. Inspired early in his life by folk art environments and artists who elevated found objects into fine art, Zagar embraced recycled fragments, mirrors, and ceramics as the foundation of what became his life’s work, transforming Philadelphia into a living mosaic museum. When the Magic Gardens site later faced demolition, community fundraising and private support preserved it, a powerful testament to the community’s belief in art.

SCH art classes across the divisions have also taken students to explore Philadelphia’s Magic Gardens to experience an example of what an artist can achieve in this medium. “It’s an art environment─joyous, colorful, unusual. I also wanted to give the students a different outlook on art, to expose them to something non-traditional,” shared Isaq Deis, former Lower School visual art teacher, after a 2nd-grade boys’ visit.

Over the course of his career, Zagar completed more than 200 murals throughout Philadelphia, each contributing to the city’s identity as a place where art lives in public view and in everyday spaces.

On February 19, 2026, Isaiah Zagar passed away, leaving behind a legacy that will continue to shape generations of artists and spark wonder in all who experience his work. 

At SCH, we are profoundly grateful for the way Isaiah Zagar’s vision and creativity fill our halls, inspiring students to imagine boldly, create joyfully, and see possibility in every fragment.
