Praia Santiago Cape Verde. Head off into the interior and you’ll find mountain peaks and fertile valleys of manioc and banana. If you only have one day in Santiago, then you should definitely visit the archipelago’s oldest settlement Cidade Velha, which became a UNESCO World Heritage site in 2009. Nowadays a charming village along the coast, the area attracts a lot of people, wanting to visit the fort which overlooks the village, the churches, and the Pelourinho a 16th-century pillory used to punish slaves.
