In tandem with the restoration of the dome itself, the existing exterior casement was restored and opened to provide natural lighting for the stained glass dome. Additionally, a new artificial lighting system was designed by the museum’s lighting and design consultant, Gordon Anson. The system was installed in the attic area above the stained glass to provide an even illumination for the dome on overcast days and at night. The interior of the attic area was painted white to provide a reflective surface to enhance the dome lighting.
