Fort of Coimbra

Fort of Coimbra is a fortress along Rio Paraguai built with thick stone walls and multiple artillery positions overlooking the strategic waterway. The structure shows the overall layout of a colonial military installation with its defensive arrangement.

The installation was founded in 1775 and served as a crucial military outpost for Portuguese control of the waterway. In 1864, Paraguayan forces captured the fortress in a three-day battle against Brazilian defenders.

The fort displays Portuguese military design adapted to South American conditions, showing how European eighteenth-century fortification ideas were adjusted for the region. Visitors can observe the stone walls and gun positions that reveal this architectural approach.

A visit requires arrangements through tour agencies in Corumbá because the fortress is only reachable by water. The journey combines a long boat ride with guided tours exploring the fortification.

The fortress holds 31 original artillery pieces from the colonial period, though only 12 remained operational during the Paraguay War. This collection of guns offers insight into the armament and combat capacity of the original garrison.
