Fort de Kock, Colonial fort in Bukittinggi, Indonesia

Fort de Kock is a fortification in Guguak Panjang, a settlement in Bukittinggi in Indonesia, built on top of Bukit Jirek hill. Remains of defensive walls, moats, and 19th-century cannons mark the grounds, which offer a wide view over the town below.

Captain Bouer founded the fort in 1825 during Dutch colonial rule to protect five nearby villages against the Padri movement. The installation later changed roles several times and served as a base during the Japanese occupation in World War II.

The fort gave its name to the settlement that grew around it, and the city kept the name Fort de Kock until it was renamed Bukittinggi after independence. Minangkabau custom calls the Dutch land seizures "tajua nagari ka Bulando", meaning the country sold to the Dutch. Since the 2002 refurbishment the hill has held the Bukittinggi City Park and a Tropical Bird Park.

A walking path from the town center leads up to the grounds, which are now open as a public park with playgrounds and sports areas. The visit works best in the morning or late afternoon, when the sun is less intense and more locals are out.

The fort was first called Sterrenschans, meaning star-shaped sconce, for its plan; it was renamed after Baron Hendrik Merkus de Kock, commander of Dutch forces and lieutenant governor-general of the Dutch East Indies. A 20-metre white-green radio antenna building now stands at the centre of the mound, with a deck on top used as a viewpoint over Bukittinggi.
