The Sheikh Lotfollah Mosque, facing Ali Qapu across Naqsh-e Jahan Square, is a jewel of Safavid architecture, celebrated for its exquisite tilework and the famous peacock that appears in the light of its intricately patterned dome. Built as a private royal mosque without a courtyard or minarets, this ticketed masterpiece of subtle colour and design is considered one of the finest buildings in Iran.
