Aruba’s Buried History: The Story of Secret Tunnels

Fort Zoutman, Aruba’s oldest standing building, comes with tales of pirates, lighthouses, and secret tunnels woven into its coral-stone walls.

Walk through the thick-walled rooms of that 1798 fortress today and you will find a museum of colonial life, antique kitchen replicas, and the Willem III Tower overlooking Oranjestad. What you will not find — at least not easily — is any clear evidence of the tunnels that local stories have whispered about for generations. The question is straightforward: Are those tunnels real, or are they the kind of embellishment that attaches itself to old buildings like barnacles on a hull? And if they are real, what do they tell us about Aruba’s layered, often invisible history?

Quick-Reference: Layers of Aruba’s Buried History

The table below maps the major historical layers that sit beneath modern Aruba, including the elusive tunnel lore. Each layer has a different kind of evidence and a different relationship to the idea of “buried” history.

Each layer represents a different kind of “buried” history — some are literally underground while others are buried in the sense of being forgotten, undocumented, or dismissed as legend.

Fort Zoutman and the Tunnel Lore

Fort Zoutman was built in 1798 with coral stone and red shutters, serving as a garrison, courthouse, and police headquarters before becoming a museum. Its Willem III Tower was added in 1868 as a lighthouse. The building is the oldest standing structure on the island, and like many old fortifications in the Caribbean, it has accumulated stories that go beyond its official history. One of those stories involves tunnels — passages said to run from the fort to the coast, used by pirates or smugglers, or perhaps as escape routes during sieges.

The problem is that no physical tunnel has been documented at Fort Zoutman in any official archaeological survey or restoration report. The stories circulate in guidebooks, travel blogs, and local anecdotes, but they lack the kind of material evidence that would satisfy a historian. That does not mean the tunnels never existed — only that they remain in the realm of plausibility rather than proof. Many Caribbean forts had underground passageways for moving supplies or personnel discreetly, and Aruba’s role as a trade hub in the 18th and 19th centuries would have made smuggling routes useful.

What remains unresolved is whether the tunnel stories preserve a genuine memory of a structure that has since been sealed or collapsed, or whether they are a narrative invention that grew around a building with a long, opaque history. Either way, the question is still open — and that uncertainty is itself a useful reminder of how much of Aruba’s history remains undocumented.

For a broader look at the island’s Indigenous foundations, including the Caquetío people who lived here long before the fort was built, see Aruba’s Hidden History: Uncovering the Island’s Amerindian Roots.

Deeper History: The Caquetío Layer

Long before any European set foot on Aruba, the Caquetío people — part of the broader Arawak cultural group — lived along the coast and inland areas, fishing, farming, and trading with neighboring islands. The National Archaeological Museum Aruba (MANA), housed in the old Ecury family house in Oranjestad, holds artifacts from this period dating to around 2500 BC. That means some of these objects are older than the Egyptian pyramids.

What makes this layer “buried” in a different sense is not that it is underground — though many Caquetío sites are — but that it is often invisible in the way Aruba presents itself to visitors. The island markets beaches, resorts, and Carnival far more prominently than its Indigenous heritage. Cave drawings, shell middens, and stone tool scatters do exist across the island, but they are rarely signposted or integrated into the tourist infrastructure. The Caquetío presence is not lost, but it is easy to miss.

For a more detailed look at the Caquetío people and their material culture, see Aruba’s Caquetío Roots: Unearthing Indigenous Heritage on the “One Happy Island”. The living traditions that descend from this heritage, including the Dera Gai festival, are explored in Beyond Beaches: Experiencing Aruba’s Dera Gai Festival and Its Ancient Roots.

Colonial and Industrial Layers

Aruba’s colonial period began with Spanish exploration in 1499 and shifted to Dutch control in 1636. The economy during the 19th century revolved around agriculture, gold mining, and aloe cultivation. Each of these activities left physical traces — some visible, some underground. Gold mining, for instance, involved digging shafts and tunnels into the island’s interior, and several abandoned mines still exist near the north coast. These are genuine tunnels, though they are industrial rather than military or piratical in origin.

Aloe processing also required underground or semi-subterranean storage spaces. Aruba was a major exporter of aloe resin — sometimes called “green gold” — and the Aloe Factory and Museum in the Hato district documents this history with displays of antique harvesting tools, processing equipment, and the fields where the plants are still grown. While no secret passages are associated with the aloe industry, its story is another kind of “buried” history: an economic boom that has been largely forgotten in the era of tourism.

The 20th century brought the oil refining industry, which transformed Aruba’s economy and society. Large refineries attracted international workers and built the multicultural character of the island today. The oil era left behind infrastructure above ground rather than tunnels, but it represents another layer of buried history in the sense that the industrial past is now overshadowed by tourism. For a guided exploration of Aruba’s cultural layers — including colonial and industrial sites — consider a culture-focused tour of the island.

Context and Comparison: What Counts as Buried History

The term “buried history” can mean different things depending on which layer of Aruba’s past you are examining. The table below compares the four layers across several attributes.

Another useful comparison is between insider and outsider perspectives. Local residents who have lived near Fort Zoutman for decades often have family stories about the tunnels, but these accounts vary widely — some describe passages leading to the harbor, others mention collapsed cellars that were never reopened. Visitors, by contrast, encounter the tunnel stories through guidebooks and blogs, where the details tend to be more dramatic and less specific. This gap between local oral tradition and published lore is itself a kind of buried history.

Questions Readers Ask About Aruba’s Secret Tunnels

Do the secret tunnels at Fort Zoutman actually exist?

No physical tunnel has been confirmed by archaeological survey or restoration work at Fort Zoutman. The stories are persistent but unverified. Some local historians believe they refer to collapsed cellars or drainage channels that have been misremembered as tunnels.

Were the tunnels used by pirates?

This is the most common embellishment. While Aruba’s location made it a stopover for trade and smuggling in the 18th and 19th centuries, there is no documentation linking Fort Zoutman specifically to pirate activity. The pirate connection is almost certainly a later narrative addition.

Where else can I find tunnels or underground spaces in Aruba?

Abandoned gold mine shafts exist near the north coast, but they are not maintained for visitors and can be dangerous. The Aloe Factory and Museum has some underground storage spaces from the aloe-processing era. Neither is connected to the Fort Zoutman lore.

What is the best way to learn about Aruba’s buried history?

The National Archaeological Museum Aruba (MANA) offers the most substantive collection, with artifacts from 2500 BC to the colonial period. Fort Zoutman’s museum covers the colonial and military story. A culture-focused tour can help connect these sites.

Why do the tunnel stories persist if there is no evidence?

Old buildings with opaque histories attract storytelling. The combination of a fortification, a lighthouse, and a long institutional past creates a natural stage for legends. The persistence of the stories tells us more about how people relate to history than about what is actually underground.

What the Tunnel Stories Reveal About Aruba’s Past

The secret tunnels of Fort Zoutman may never be found — they may never have existed in the way the stories describe. But that does not make the stories irrelevant. They point to something real: the gap between what is documented and what is remembered, between the history that is preserved in museums and the history that survives in conversation. Aruba’s buried history is not a single secret waiting to be uncovered. It is a series of layers — Indigenous, colonial, industrial, folkloric — each with its own kind of visibility and its own relationship to evidence. The tunnels, real or not, are a reminder that every old building and every stretch of coastline has more stories than any archive can hold.
