Banten Lama’s preservation question is no longer limited to historic walls and artefacts. The Great Mosque, Avalokitesvara Temple, pilgrims, residents, traders and public authorities all shape how the heritage landscape can remain protected and usable.
Banten’s disaster memory is being carried from oral history and commemorative traditions into school outreach, field exercises, warning equipment and evacuation planning. In Pandeglang’s Sumur district, a BMKG field school held on 18 October 2025 shows how lessons from the 22 December 2018 tsunami are being converted into practical risk education.
At Banten Lama in Serang, palaces, mosques, markets, quarters and port facilities show how a sixteenth- to eighteenth-century trading city absorbed people, practices and building ideas from across Asia and Europe.
The Sunda Strait links the Java Sea and Indian Ocean while concentrating three kinds of history: volcanic risk around Krakatau, trade and ferry movement between Merak and Bakauheni, and wartime naval conflict in 1942.
The 1883 Krakatau catastrophe is documented by ship logs, scientific expeditions, physical evidence and tsunami records. Anak Krakatau’s latest verified 2026 activity shows why that history still matters, while modern seismic, deformation, satellite, sea-level and aviation monitoring provides a much stronger warning system.
Banten Lama’s history becomes clearer when read as a connected water-and-landscape system: the Cibanten reaches the coast at Karangantu, while mosques, palace ruins, a fort and waterworks mark the former port city’s political and commercial core.
Banten Lama’s port and the Serang-area political centre connected western Java with Sumatra, Asian markets and European shipping. Verified sources explain the role of pepper, Karangantu, customs, markets and the Banten Sultanate, while leaving modern trade-volume claims unconfirmed.
Banten’s selection as host of Indonesia’s 2026 Disaster Risk Reduction Month puts a national preparedness agenda in a province shaped by centuries of earthquakes, volcanic tsunamis, floods and landslides. The 13–15 October programme links that history to current planning, while leaving its post-event results to be assessed.
Banten’s latest preservation efforts are moving beyond repaired buildings. The harder test is whether Banten Lama’s mosques, palaces, museum and fortifications remain connected to the worship, pilgrimage, education and local business that keep the old city meaningful.
The Sunda Strait has been a passage, battlefield and disaster zone. Its strategic importance today rests on the same geography—and on Indonesia’s ability to keep ships moving while managing volcanic and tsunami risks.
