The Masjid Agung Demak (Great Mosque of Demak) is arguably the most historically important and sacred mosque in Java, located in Demak, Central Java, and deeply tied to the founding of the Demak Sultanate and the work of the Wali Songo (Nine Saints) in the 15th century. It embodies the classic Traditional Javanese Mosque architecture, notably featuring a distinct three-tiered pyramidal roof (tumpang), which symbolizes the philosophical concepts of Iman, Islam, and Ihsan.
