The knowledge of cultural heritage in a specific region is a basic element for the development of actions and skills necessary to save and manage. The historic set of Cidade Velha, classified as a World Heritage Site, still preserves traces that allow its conservation. In this sense, a first approach to the Archaeological Map of Cidade Velha is presented, with the identification and inventory of all vestiges, within the protected area of the site, which encompasses the Ribeira Grande valley and the historic center, and represents mainly as primordial populated areas, and urban expansion in the 16th and 17th centuries. The vestiges identified are authentic testimonies of cultural diversity that characterize a historic trajectory of the Cidade Velha.
