Ara to the Sun and the Ocean (Alto da Vigia, Sintra)
On a promontory north of Cabo da Roca (the Promonturium magnum for the Romans), close to the mouth of the Colares River, we find an archaeological site where the Muslims built, in the 11th century AD, a small ribat (religious and military complex) on the ruins of a temple in which the Romans worshipped the Sun, the Moon and the unknown Ocean (ignotus oceanus), most likely from the second quarter of the 1st century AD.
