History
According to the historian Wolfgang Born, the onion dome has its origin in Syria, where some mosaics from the Umayyad Caliphate depict early stages of the development of bulbous domes. An early prototype of onion dome also appeared in Chehel Dokhter, a mid-11th-century Seljuk architecture in the Damghan region of Iran.
