Forte do Príncipe Real (also: Forte da Preguiça) is a ruined fort in the village of Preguiça in the island of São Nicolau, Cape Verde. It was built in 1820 to protect the roadstead and village of Preguiça.^[1] It sits at about 50 m elevation, at the waterfront. It was abandoned in the first decades of the 20th century, and other buildings (houses, a school) were built on top of its remains. In the 1990s these buildings were cleared, and the fortress was excavated.^[1]
