Registan Square, a UNESCO World Heritage site in Samarkand, Uzbekistan, is a breathtaking ensemble of three madrasahs (Ulugbek, Sher-Dor, and Tilya-Kori) offering a deep dive into Timurid architecture and Islamic scholarship. The site is generally accessible, though entry into some madrasah rooms or climbing minarets may involve steps; the main square is flat and easily navigated. While splendid for solo exploration with available information, a guided tour is highly recommended to unlock the rich history and intricate symbolism of each structure. It's open year-round, with spring and autumn providing the most pleasant weather, though summer evenings and winter offer unique, less crowded experiences. Expect an entrance fee of approximately 50,000-70,000 UZS (about $4-6 USD) for foreign tourists, and budget 2-4 hours for a comprehensive visit. Don't miss the captivating evening light and sound show (seasonal), and remember to dress modestly out of respect for the historical and religious significance of the site.
