Aga Khan Mosque (also known as the Ismaili Jamatkhana) in Stone Town of Zanzibar is the earliest Shi'a-Ismaili place of worship on the island, originally built in 1838 and significantly expanded in 1905. Set within a spacious courtyard and topped with minimalistic arabesque façades and pointed windows, the mosque stands out for its carved Gujarati-style wooden entrance doors—shipping craftsmanship from India during its construction. As one of the larger mosques in the Kiponda district, it continues to serve the Ismaili community, while offering travelers a chance to appreciate a distinctive chapter of Zanzibar's 19th-century religious and cultural connections across the Indian Ocean.
