The lighthouse was commissioned to commemorate King Willem III of the Netherlands.
The structure is composed of vertical cast-iron segments bolted together, a signature technique of 19th-century European lighthouse engineering.
Its primary historical purpose was to guide ships through the hazardous waters of the Sunda Strait following the catastrophic 1883 Krakatoa eruption.
The lighthouse has withstood over 140 years of exposure to salt air and tropical weather.
It was strategically positioned at the gateway to the Sunda Strait, one of the world's most critical maritime corridors.
The Cikoneng Lighthouse, also known as the Willem III Lighthouse, is an 1885 colonial-era navigation tower located on the coast of Banten. It was constructed by the Dutch government to monitor maritime traffic passing through the Sunda Strait. The structure stands 75 meters tall, built with cast iron plates that were transported directly from the Netherlands. It remains an active lighthouse managed by the Indonesian Ministry of Transportation. Visitors can climb the internal spiral staircase to reach the observation gallery. The site serves as a memorial to the eruption of Krakatoa in 1883, which necessitated improved coastal navigation in the region. The surrounding grounds include a small park area and access to the adjacent beach. It is one of the few surviving Dutch-built lighthouses in Indonesia that retains its original structural integrity.
From the base looking straight up to capture the geometric patterns of the cast-iron plates, or from the top gallery looking toward the horizon.
Wear athletic shoes with good grip, as the internal iron stairs can be steep and slippery.
Bring a bottle of water, as there are no hydration stations inside the lighthouse tower.
Plan your climb for cooler hours to avoid the intense heat trapped within the iron structure.
Do not attempt to climb during high-wind weather conditions or thunderstorms.

Maintain a respectful tone as the structure is a functioning government facility; refrain from touching the light mechanism.
