Our first stop is Praia do Guincho. A popular beach that has the Blue Flag (an international award given annually since 1987 to beaches and marinas whose water meets high quality standards and is suitable for safe bathing). Fans of water sports will like this beach especially.
In addition, the beach was featured in the sixth series of the Bond movies, On Her Majesty's Secret Service. It's nice to note that the appearance of the beach has not changed since 1969.

If you surf professionally, you might be familiar with this place. One of the most extreme spots in Portugal. On days when the spot works, the initial wave height is 3 meters.
For everyone else it is a very beautiful place, where it is definitely worth to stay and take some pictures.

The fort was completed in 1648, and the construction of the defensive line on the coast began in 1640, just after the Restoration of Independence from Spain.
In the fort you can discover the history of the defense of the coast of Cascais from the fifteenth to the nineteenth century and the life of its inhabitants.

Not for nothing this place is called "Devil's Mouth" - the waves hit the rocks with incredible force and create a very strong noise.

It's time for lunch. And we will spend it in the fish restaurant, which is located on the pier.

The museum is dedicated to the work of Paula Rego, a British artist of Portuguese origin. The dramatic and monumental nature of the artist's work makes her work a notable phenomenon of figurative painting of the 20th century. The exhibition tells the story of more than 50 years of her work.
Her husband, the painter Victor Villing (January 15, 1928-June 1, 1988) is also represented.

São Julião da Barra is by far the most complete and well-preserved fort built by the eminent military engineer Sébastien Le Pretre de Vauban. The fortresses he built have been declared World Heritage of Humanity.

Monument to soldiers of World War I.

We will go to another Portuguese restaurant for dinner. It's hard to say which is more important: the delicious fresh seafood or the peaceful silence and view of the river. Perhaps one is meaningless without the other.
