Baiturrahman Grand Mosque is a Mosque located in the centre of Banda Aceh city, Aceh Province, Indonesia. The Baiturrahman Grand Mosque is a symbol of religion, culture, spirit, strength, struggle and nationalism of the Acehnese people. The mosque is a landmark of Banda Aceh and has survived the 2004 Indian Ocean tsunami.

The original Mosque was built in 1612 and featured a multi-tiered thatched roof, a typical feature of Acehnese architecture. However, in 1873 the mosque caught fire during the First Aceh Expedition.

The mosque was designed by the Dutch architect Gerrit Bruins in 1879 and completed in 1881. The design was subsequently adapted by L.P. Luijks, who also supervised the construction work done by  contractor Lie A Sie. The design chosen is Mughal revival style, characterized by grand domes and minarets. The unique black domes are constructed from hard wood shingles combined as tiles.

The interior is decorated with relieved wall and pillars, marble staircase and floor from China, stained-glass windows from Belgium, well-decorated wooden doors, and ornate bronze chandeliers. The building stones are from the Netherlands. At the time of its completion, this new design presented a stark contrast compared with the original mosque that many Acehnese refused to pray in the mosque, because it was built by the Dutch “infidels”. Today however, the mosque has become the pride of Banda Aceh.

More features were added to the mosque. Before 1935, the new Baiturrahman Grand Mosque featured one dome and one minaret. More domes and minarets were added afterwards in 1935, 1958 and 1982. Today, the mosque has 7 domes, 8 minarets (including the highest in Banda Aceh.) and 32 pillars.
