Willet Studios restored John La Farge’s Isaiah Rose Window at First Unitarian Church of Philadelphia, reuniting and stabilizing the landmark work after nearly three decades in storage. The project preserved its structural integrity, painterly detail, and historic significance.

Originally created around 1900, La Farge’s rose window required extensive structural rebuilding due to metal fatigue and complex layered construction. Over three months, Willet’s team conserved original painted details—most notably Isaiah’s face—restoring the masterpiece to its intended brilliance and earning a 2022 Preservation Achievement Award.
