The Nasir al-Mulk Mosque, also known as the Pink Mosque, is a stunning architectural gem in Shiraz, Iran, famous for its vibrant stained glass windows that create a mesmerizing kaleidoscope of colors, especially during the morning light. It is recommended to visit independently to appreciate the tranquil atmosphere and intricate details at your own pace, but guided tours can provide insightful historical context about its Qajar-era architecture. The best time to visit is early morning, typically from 8:00 to 10:00 AM, to witness the full splendor of the sunlight through the stained glass. While there are no specific seasonal restrictions, spring (March to May) offers mild weather, ideal for exploring Shiraz. Entry tickets cost approximately 2-5 USD, with a typical visit lasting about one to two hours. The mosque is accessible by taxi or local transport from Shiraz's city center, and it's advisable to dress modestly, in accordance with local cultural norms.
