The Nasir al-Mulk Mosque, also known as the Pink Mosque, in Shiraz, Iran, is renowned for its stunning stained glass windows, which create vibrant, colorful patterns across the interior when the morning sunlight streams through. It's best visited in the early morning for optimal lighting effects. Access is relatively easy, and it is situated in a safe part of Shiraz, often combined with a visit to the nearby Vakil Bazaar. While guided tours can enhance the experience by providing historical context, independent visits are also feasible. The entrance fee is modest, around 150,000 Iranian Rials for international visitors. Typically, you’ll need about one to two hours to fully explore and appreciate the mosque. Shiraz enjoys a mild climate in spring (March to May) and fall (September to November), making these seasons ideal for a visit. It’s advised to check opening hours and any potential restrictions in advance, as religious holidays can affect visitor access.
