Sal Rei, Boavista, Cape Verde IslandsSal Rei (literally "Salt King"), with a population of about 3,000 inhabitants, is Boavista's capital. The town was originally known as Porto Ingles, probably due to the English sailors that established a salt business on the Island in the 1600s. The Duque de Braganca fort, which faces Sal Rei from the nearby islet (Ilhéu de Sal Rei), was built to protect the port from the frequent pirate attacks that plagued the Island during the early 1800s. Apparently, it is possible to swim the 1.5km to this Islet from Sal Rei, though you can also take a boat.
The town itself is a dusty, backward, laid-back sort of place with cobbled streets and slightly decaying colonial buildings, however Sal Rei is changing fast as apartments, hotels and villas are being built for the expected tourist boom.
