Yale University Sterling Library

New Haven, CT

Yale University’s largest library, the Sterling Library was completed in 1930. Constructed in the Collegiate Gothic style, this library mimics the style of a Gothic Cathedral. The beauty of this library is evident in both the towering architecture and the details of the stained glass windows, which display stories from acclaimed works of literature.

EverGreene restored 40 monumental stained glass windows designed by the renowned artist G. Owen Bonawit. This restoration project encompassed partial releading of panels, replication of missing panels, and in situ repair of broken glass, damaged leads and the failing support system. EverGreene also executed the design, fabrication and installation of new protective glazing system.

Yale was initially under the impression that these windows, which are adorned on the interior with complex lead sheet overlays, could not be saved. However, with EverGreene’s expertise, we developed a process whereby the original lead overlays were removed, conserved and reapplied to the windows. We are proud to have helped Yale preserve these historic elements of one of their architectural  crown jewels.
