A study in harmonious understatement, this mosque is the perfect complement to the overwhelming richness of the larger Masjed-e Shah. Built between 1602 and 1619 during the reign of Shah Abbas I, it is dedicated to the ruler’s father-in-law, Sheikh Lotfollah, a revered Lebanese scholar of Islam who was invited to Esfahan to oversee the king’s mosque (now the Masjed-e Shah) and theological school.

The dome makes extensive use of delicate cream-coloured tiles that change colour throughout the day from cream to pink (sunset is usually the best time to witness this). The signature blue-and-turquoise tiles of Esfahan are evident only around the dome’s summit.

The pale tones of the cupola stand in contrast to those around the portal , where you’ll find some of the best surviving Safavid-era mosaics. The exterior panels contain wonderful arabesques and other intricate floral designs; those displaying a vase framed by the tails of two peacocks are superb. The portal itself contains some particularly fine muqarnas with rich concentrations of blue and yellow motifs.

The mosque is unusual because it has neither a minaret nor a courtyard, and because steps lead up to the entrance. This was probably because the mosque was never intended for public use, but rather served as the worship place for the women of the shah’s harem. The sanctuary or prayer hall is reached via a twisting hallway where the eyes become accustomed to the darkness as subtle shifts of light play across deep blue tilework. This hallway is integral to both the design and function of the mosque because it takes the worshipper from the grand square outside into a prayer hall facing Mecca, and thus on a completely different axis.

Inside the sanctuary you can marvel at the complexity of the mosaics that adorn the walls and the extraordinarily beautiful ceiling, with its shrinking, yellow motifs. The shafts of sunlight that filter in through the few high, latticed windows produce a constantly changing interplay of light and shadow.

The mihrab is one of the finest in Iran and has an unusually high niche; look for the calligraphic montage that names the architect and the date 1028 AH. Photography is allowed but using a flash is not.
