Aceh Sultanate
In the 19th century, the sultanates of Indonesian archipelago began to adopt and absorb foreign influences of Islamic architecture, as alternative to Javanese style already popular in the archipelago. The Indo-Islamic and Moorish style are particularly favored by Aceh Sultanate and Deli Sultanate, as displayed in Banda Aceh Baiturrahman Grand Mosque built in 1881, and Medan Grand Mosque built in 1906.
