The Sheikh Lotfollah Mosque is located to the east of Imam Square. It is an exquisite religious building, which was built in 1602 and completed in 1619. It was built by the king for the Lebanese scholar Sheikh Lotfollah. The huge dome, deep blue wall decorations with gentle Arabic patterns, are truly magnificent. The best time to visit Sheikh Lotfollah Mosque is when the climate has distinct four seasons. The northern part is relatively cool in spring, summer, and autumn, and cold in winter, while the southern part is hot in summer and warm in winter. The highest temperature is in July, with average lows and highs of 22°C and 37°C, and the lowest temperature is in January, with average lows and highs of 3°C and 7°C. All four seasons are suitable for tourism. Historically and culturally, Sheikh Lotfollah Mosque, built by the emperor in honor of the great Shiite Muslim scholar, who was also the father of the queen and a famous scholar in Lebanon, Sheikh Lotfollah, is smaller in scale compared to the Imam Mosque, but its exterior is luxurious and the interior is exquisite, not inferior to the Imam Mosque at all. This is because the Imam Mosque is used for large-scale religious activities, while the royal family’s daily religious activities mostly take place in Sheikh Lotfollah Mosque. It is said that there is an underground passage from the Ali Qapu Palace to the Sheikh Lotfollah Mosque, making it convenient for the queen and other female members of the royal family to visit without having to appear in public.
