javaprivatetour.com – Welcome to Onrust Island, a hidden gem in Indonesia’s rich maritime history. While most people think of Jakarta’s Old Town (Kota Tua) or Sunda Kelapa Harbor when discussing colonial history, there’s another crucial piece of Batavia’s past floating in the waters of the Thousand Islands—Onrust Island.
Once a bustling shipyard and naval base for the Dutch East India Company (VOC), Onrust played a major role in maritime trade and shipbuilding in the 17th and 18th centuries. This tiny island wasn’t just another colonial outpost; it was home to some of the most skilled shipbuilders in the world. Let’s take a deep dive into the incredible story of Onrust, where ships were built, repaired, and legends were made.
The Origins of Onrust Island

Back in the early 1600s, the Dutch VOC was determined to dominate the lucrative spice trade. To solidify their presence in Java, they needed a strong naval base to support their fleet. Enter Onrust Island.
In a strategic negotiation with Prince Jayakarta, the VOC secured rights to use the island in 1610. By 1613, they had built a massive shipyard, transforming Onrust into a vital hub for ship maintenance and repairs.
The island’s name, “Onrust,” means “restless” in Dutch, which perfectly described the never-ending activity here. However, while the Dutch called it Onrust, the locals simply referred to it as Pulau Kapal (Ship Island), due to the sheer number of vessels docking and departing daily.
A Key Hub for Shipbuilding and Repairs
The shipyard on Onrust was more than just a dock—it was a fully equipped naval facility. Ships traveling from Europe to the East Indies endured months at sea, often arriving in dire need of repairs. The island had warehouses filled with essential supplies, including spare parts, ropes, and timber sourced from nearby forests.
Dutch records describe Onrust as the most efficient shipyard in the tropics. Skilled local craftsmen, along with experienced Dutch engineers, worked around the clock to build, maintain, and repair ships that traveled across the world.
The World’s Best Shipbuilders—Right Here in Java
Onrust’s reputation for excellence reached far beyond the Dutch East Indies. Even Captain James Cook, the legendary British explorer who discovered Australia, was forced to make an unplanned stop at Onrust in 1770.
After months at sea, his ship, the Endeavour, was in desperate need of repairs. The shipbuilders at Onrust worked their magic, and Cook was so impressed that he declared Onrust one of the best shipyards in the world. In his own words, “There is no better shipyard anywhere than Batavia.”
Dutch missionary and historian Adolf Heuken also noted that Onrust’s shipbuilders could repair any type of vessel, whether it was an Arab dhow, a British bark, a Dutch Oost-Indiëvaarder, or a Chinese junk.
Life as a Shipbuilder on Onrust
Working on Onrust wasn’t easy. The shipbuilders—mostly skilled Javanese carpenters—labored under tough conditions, often receiving low wages despite their expertise. Meanwhile, the Baas van Onrust (Head Shipbuilder) lived like a king, controlling the workforce and even profiting from selling imported ship parts at high prices.
Despite the hardships, people from across the archipelago flocked to Onrust, hoping for better opportunities. By 1775, over 2,000 people lived on the island, including Dutch soldiers, laborers, and even enslaved individuals who were forced to work in the shipyard.
The Fall of Onrust Island
Onrust thrived for nearly two centuries—until the British arrived. In 1800, the British Navy attacked Onrust, burning much of the shipyard to the ground. They returned in 1806 and 1810, ensuring that the island could no longer serve as a strategic naval base.
Then came Governor-General Daendels, a staunch admirer of Napoleon Bonaparte. Under his rule (1808–1811), Onrust was permanently abandoned. What was once a buzzing hub of maritime activity was left in ruins, with only a few foundations and gravestones remaining today.
Onrust’s Legacy and Its Modern Ruins
Over the years, Onrust saw different uses—it was a prison, a quarantine center for Hajj pilgrims, and later a forgotten piece of Jakarta’s history. With the rise of Tanjung Priok as the primary harbor in Jakarta, Onrust faded into obscurity.
Today, visitors to Onrust Island can still see remnants of its glorious past: the remains of a pier, a few crumbling walls, and weathered tombstones. One of the most famous gravestones belongs to Maria van de Velde, a young woman who died in 1721. Her poetic epitaph still stands as a haunting reminder of the island’s storied past.
