The Padri War had been simmering since the early nineteenth century. Returning from the hajj, a group of Minangkabau religious leaders sought to bring Wahhabi-influenced reform to their homeland, targeting the adat traditions they considered unislamic -- the matrilineal inheritance system, the gambling, the cockfighting, the ceremonial practices that predated the arrival of Islam. The conflict pitted village against village, reformer against traditionalist. When the adat communities invited Dutch intervention, the colonial power saw opportunity: a chance to establish military presence deep in the Sumatran interior. Fort de Kock was the result. It gave the Dutch a defensive anchor in the highlands, and from this single hilltop position, they expanded outward, establishing additional fortifications on Bukit Sarang Gagak, Bukit Tambun Tulang, Bukit Cubadak Bungkuak, and Bukit Malambung. After years of fighting, the Dutch and their adat allies prevailed. The Padri War ended, but the forts remained.

What began as a military outpost quickly outgrew its original purpose. Around the fortification on Jirek Hill, the Dutch built the infrastructure of colonial administration: government offices, a cemetery, a market, schools, and recreation grounds. A settlement coalesced, drawing people from the surrounding villages and beyond. The growing town took the fort's name, becoming Fort de Kock in official records and common usage alike. Roads were cut through the highlands; a rail line connected the city to Padang and Payakumbuh by the 1890s. The star-shaped sconce that had once been the only Dutch structure for miles was now just one feature of a thriving colonial city -- though it remained the symbolic center, the original reason any of it existed. The name Fort de Kock would persist through the Dutch colonial era, through the Japanese occupation of World War II, and through the turbulent early years of Indonesian independence, until 1949, when the newly sovereign nation renamed the city Bukittinggi.

The original buildings of Fort de Kock are gone. The star-shaped earthworks have softened into grassy contours, and the moats that once ringed the fortification are shallow traces in the landscape. Nineteenth-century cannons, salvaged and repositioned, sit atop a 20-meter radio antenna maintenance building that now occupies the center of the old fort mound -- painted white and green, it serves as a viewing platform with panoramic vistas of Bukittinggi's red rooftops and the volcanic peaks beyond. In 2002, the regional government of West Sumatra refurbished Jirek Hill, transforming the area into Bukittinggi City Park and Tropical Bird Park. The hilltop where Captain Bouer once oversaw trench-digging is now shaded by tropical trees, frequented by families and tourists rather than soldiers.

On an adjacent hill stands the Bukittinggi Zoo, known locally as Taman Bundo Kanduang, alongside the Museum Rumah Adat Baanjuang, which preserves examples of traditional Minangkabau architecture -- the sweeping, horn-shaped rooflines of the Rumah Gadang that remain one of Southeast Asia's most distinctive building forms. The Limpapeh Bridge, a pedestrian suspension span, connects the old fort grounds to this neighboring hilltop, swaying gently above the valley between them. Walking across it, you pass from colonial memory into living Minangkabau culture in a matter of steps. Below both hills, the city that the fort created carries on -- no longer Fort de Kock, no longer a garrison town, but still shaped by the hilltop where a Dutch captain broke ground two centuries ago during a war between faith and tradition.
