Every night, laser light and sound shows are projected onto the Madrasahs. They roughly start about an hour after sunset, with the best vantage point at the tiered concrete area behind Registan Square’s entrance. Visit Registan Square to capture the sunset over the madrasahs. You have about 20 minutes of natural light after sunset before the artificial lights illuminate the square and surrounding structures. Tilla Kari Park (just behind Registan Square) offers some interesting perspectives of the Registan Square madrasahs.
