Little Hagia Sophia, originally the Church of Saints Sergius and Bacchus, is a 6th-century Byzantine structure located in Istanbul. It was commissioned by Emperor Justinian I and Empress Theodora shortly before the construction of Hagia Sophia and is considered an important precursor in the development of Byzantine domed architecture. Following the Ottoman conquest of Constantinople in 1453, the church was converted into a mosque and became known as Küçük Ayasofya Camii (Little Hagia Sophia). The building retains much of its original structural design, including its central dome and octagonal plan, while incorporating later Ottoman additions such as a minaret and interior modifications for Islamic worship.
