The Jombang Mosque is famous because it is the birthplace of Nahdatul Ulama, the largest Islamic organization in Indonesia.

An old photo recording the condition of this mosque in ancient times was recorded by H. Aboebakar. He published it in the book “The History of the Mosque: and the Deeds of Worship in It” (“Sedjarah Mesdjid: and Amal Ibadah Dalamnja”) in 1955.
