الملخص الإنجليزي

The Peniche peninsula, corresponded before the twelfth century to a coastal island, separated from the continent by a wide erosive navigable channel.

The gradual silting up of the mouth of the São Domingos River built the present sandy isthmus leading to the human occupation of the island and its huge development as a harbour.

Its geology and lithology, mainly Jurassic limestones showing spectacular cliffs and carved forms such as lapis, attract thousands of tourists nowadays.

Several archaeological sites are identified in the area, such as, shipwrecks, port structures, salt marshes, nurseries, burial deposits, anchorages and an amphorae production complex.

16km West of Peniche is the Berlengas Archipelago; a group of small islands and islets.

Their geology is quite different from that of Peniche and the continent.

They correspond to Precambrian emerged submarine mountain tops, having their main ones made up of coarse grained red granite, the “Berlengas Granite”.

As such, they testify to the ancient bounding of the Gondwana continent before the separation of Europe and America, and represent the limit of a large tectonic trough in the east (Lusitanian Basin).

This paper aims to present the origins of both sites in order to contribute to our understanding of the reasons behind their particularly different history and evolution.
