No, the pyramids themselves do not naturally glow at night. However, they are often illuminated by artificial lighting during sound and light shows.
These sound and light shows are a popular tourist attraction, transforming the appearance of the pyramids after dark. During the show, the pyramids are bathed in colorful lights, enhancing their visual appeal and creating a captivating experience for viewers. A narration accompanies the light display, recounting the history and significance of the ancient Egyptian civilization that constructed these magnificent structures. The show typically lasts around an hour.
Therefore, while the pyramids don't possess inherent luminescence, they can "glow" at night thanks to carefully designed lighting arrangements.
