Ampel Mosque, Historic mosque in Semampir district, Surabaya, Indonesia

The Ampel Mosque is a white gate structure with a tall rectangular facade and a central arched opening, flanked by pilasters with circular carved motifs. Above it sits a stepped, tiered roofline topped by a squared crown. Through the archway an inner doorway and dark interior are visible; rounded pillar bases stand to the left and a small tower-like element to the right.

Sunan Ampel founded the mosque in 1421 CE; it is the oldest mosque in East Java. His tomb complex stands within the grounds, built as a walled courtyard with gateways leading up to the grave. The site lies in the Ampel sub-district of Semampir, Surabaya.

The mosque's name comes from the Ampel sub-district where Sunan Ampel settled; his tomb complex lies within the grounds, reached through three walled compounds called Jeroan, Jaba Tengah and Jaba. On the left side of the mosque is a well that believers use to strengthen a pledge or oath. The surrounding streets are lined with buildings in Chinese and Arab architectural styles.

Visitors should wear clothing that covers shoulders and knees, and be aware that prayer areas are separated by gender. It helps to be aware of daily prayer times since the mosque is most active when worshippers gather for prayers.
