This is one of the oldest mosques in Indonesia, located within the Kasepuhan Palace complex in Cirebon. It was constructed around the late 15th century during the era of the Wali Songo (Nine Saints), with Sunan Kalijaga credited as a key architect under the initiative of Sunan Gunung Jati. Its distinctive architecture features a multi-tiered roof instead of a dome and is famous for the unique tradition of "Adzan Pitu" (Seven simultaneous calls to prayer) performed before the Friday prayer.
