No part of Cape St. Vincent fits this description, but on the eastern side of Sagres Point is a harbor, Baleeira, port of the modern town of Sagres, protected by four small islands in a line (the tiny Martinhal Islets) visible in satellite imagery. At the far eastern end of the beach of Martinhal, erosion of the cliffs has exposed a series of Roman pottery kilns for fabricating transport amphoras and roof tiles.
