Columbia University performed a year-long restoration of the monumental cast iron windows by the west gallery in the Rotunda to repair deteriorating conditions. The scope of work included the removal of window frames and parts, offsite restoration, and reinstallation of the restored window frames and parts. The project improved weather proofing in addition to restoring the conditions of the window frame and parts. The west monumental window restoration follows the previous restoration of the south and east windows, with the north window to be restored in the future.
This project was completed in February 2023.
