Redoubt Duijnhoop, Military fort at Salt River mouth, Cape Town, South Africa
Redoubt Duijnhoop was a small square fort made of clay and timber, built on the shore of Salt River near its mouth close to Cape Town. The structure was equipped with two 12-pounder guns positioned to control ships entering Table Bay.
The Dutch East India Company built this fort in 1654 to protect its supply station established just a few years earlier. It formed part of a wider defense network designed to secure control of the harbor area near the main fortress.
The fort shows Dutch military architecture from the colonial period, with European fortification methods combined with local materials like clay and timber. This blend of building techniques reflects how Dutch settlers adapted their defensive designs to the South African environment.
The site was positioned at a strategic location at the river mouth, where visitors can understand how the guns controlled the waterway. The ground is relatively flat and easy to navigate, though only ruins remain of the original structure today.
The fort operated for only about 18 years before it had to be abandoned in 1672 as the clay structure deteriorated rapidly. This brief existence makes it a rare example of a fortification whose failures forced colonists to reconsider their building methods.
