Coastal heritage

Fort Lodewijk

Daendels had this fort built in 1808 to guard the mouth of the Madura Strait. Only ruins remain, at the edge of the water.

History

The fort was built in 1808 on the orders of Governor-General Herman Willem Daendels and named after Lodewijk (Louis) Napoleon, then King of Holland. Historical records describe it as the only fort Daendels managed to complete in the archipelago. It guarded the coast at the mouth of the Madura Strait until 1857. That year the Dutch dismantled it and moved the defence centre to Surabaya, which ended its use as a fort; the ruins stayed where they were. Construction was supervised by Arnold Adriaan Buyskes, who took command of the naval and land forces in Surabaya on 6 December 1808.

A changing coastline

On a Dutch map from the 1870s, a fort at this spot is labelled Fort Erfprins and stands on an islet about 0.8 km offshore; it is matched to Fort Lodewijk by its position, since no record of a renaming has been found. By the 1920s–1930s aquaculture ponds had been built out to the fort. Erosion is now eating those ponds away, and the ruins stand at the waterline again.

What remains

Foundations, two wells and brick ruins under a banyan tree; part of the site has been lost to erosion. It was listed as a Gresik regency heritage site on 21 October 2020.

The fort and the new restoration site

The 2026 mangrove restoration site lies next to the fort area. Restoring the eroded ponds here also helps protect the coastline around the heritage site. About the restoration →
