:: S. Martinho

The current bay of S. Martinho is the last vestige of an ancient Golf which, until the 16th century, extended itself inwards to Alfeizerão. It opens to the ocean through a small mouth, around 180 meters large, between the hills of Santana, to the South, and the Lighthouse, to the North (check the photos below).From the top of the belvederes of Facho and Cruzeiro, near the Chapel of Saint Anthony, it is a pleasure to take a look at the bay coloured by the typical yellow fishing boats and by the silvered track of small recreational ones.

The town, founded by the monks of the Monastery of Alcobaça at the 13th century, goes down in the shape of an amphitheatre from the hillside to the Dock, in the northern corner of the Beach. Over recent years it was progressively extended through the Marginal Avenue to the dunes of Salir. Its ancient houses can be discovered by climbing the D. Pedro V lane to the scenic spot of José Bento da Silva Square, or to the Main Church, from the 18th century.

S. Martinho do Porto has many possible walking routes, esplanades, pubs and restaurants for you to discover. The sea is astonishingly quiet and the beach a paradise for children and nautical sports.
