From 2018 to 2019, a $22 million restoration of the Great Hall, including restoring original detailing and rebuilding the large skylight was completed, increasing natural light by 50 to 60 percent. The skylight, originally built in the 1920s, took on decades of harsh weather, leading to countless patchwork repairs, many of which blocked light from entering the Great Hall. The 2018–19 renovation restored the historic skylight to its original appearance, and added another glass skylight atop it. The new skylight is better-designed to prevent water and snow damage, and increases light entering the Great Hall.
