Van der Wijck Fort, Military fort in Gombong, Indonesia.

Van der Wijck Fort is an octagonal fortification in Gombong built with red brick and spanning two floors. The structure features strategic observation points positioned at elevated ground to monitor the surrounding area.

Built around 1820 by order of General Van den Bosch, the fort first served as a military storehouse during the Java War (1826–1830). It was named Fort Cochius after Frans David Cochius, commander of the Dutch East Indies army in 1835. In 1856 the Military Pupil School moved in, and the name changed to Van der Wijck. Japan used it as a food and weapons depot in World War II, and since 1984 part of the fort has housed a cadet school and a hotel.

The fort is named after Carel Herman Aart van der Wijck, Governor-General of the Dutch East Indies from 1893 to 1899; his name appears on the right-hand door. It was earlier called Fort Cochius after Frans David Cochius, its commander. Since 1984 part of the building has housed a cadet school and part a hotel, and a small tourist train runs on the stone roof.

The fort is accessible daily and sits on elevated ground, so visitors should expect slopes and stairs when exploring. The site also offers additional facilities including train rides and swimming areas for those wanting to spend more time there.

The fort's walls are 1.4 metres thick, and the building stands about 10 metres high; the octagonal plan is the only one of its kind in Indonesia. Inside are 16 large barracks rooms of 7.5 by 11.32 metres plus some fifty smaller rooms. The upper floor once held a covered gallery, now used by the tourist train that circles the roof.
