Masjid Jami Keraton Sambas, Royal mosque in Sambas Regency, Indonesia.

Masjid Jami Keraton Sambas, officially Masjid Sultan Muhammad Syafi'oeddin II, stands in the palace complex of the Sambas Sultanate in Sambas, West Kalimantan. The mosque has eight central pillars, and the entire building is made of belian wood. It is recorded as the oldest mosque in West Kalimantan.

Sultan Umar Aqomuddin established the mosque between 1702 and 1727 as the spiritual center of his sultanate. His son Sultan Muhammad Saifuddin later expanded the building into a grander structure.

The mosque's official name honours Sultan Muhammad Syafi'oeddin II, and it stands inside the Sambas sultanate's palace compound. Its eight central pillars are read as a reference to the founding sultan, the 8th or 14th of the Sambas line, so the building itself records the dynasty's genealogy.

The mosque stands inside the Sambas royal palace compound in Sambas town, West Kalimantan. It remains an active place of worship, so time your visit outside prayer times and wear modest clothing when entering the prayer hall. The building is entirely of wood, including the eight central pillars.

The entire building is constructed from belian wood, a durable local timber that grows in Kalimantan forests and resists decay for centuries. This choice of material reflects both practical wisdom and the craftsmanship traditions of the region.
