Caxias Beach

Highlight • Beach

The Fort of São Bruno is situated on the estuary of the River Tagus in Caxias, Oeiras municipality, near Lisbon in Portugal. It was built in 1647 and became operational in 1649 as part of the construction of a line of forts to control access to Lisbon, which stretched from Cabo da Roca on the Atlantic coast to the Belém Tower near Lisbon. The fort is well preserved, following its original design, and is considered one of the most attractive examples of maritime military architecture on the Portuguse coast. It presently serves as the headquarters of the Associação Portuguesa dos Amigos dos Castelos (Portuguese association of friends of castles).
During the Portuguese Restoration War, King John IV of Portugal identified the need to strengthen Lisbon's defences in the face of attacks by the Spanish navy. In 1647 he ordered construction of a fort at Caxias to improve the defence of the right bank of the Tagus by making possible crossfire with the Fort of Nossa Senhora do Vale (Our Lady of the Valley) to the east, now demolished, and the Fort of Giribita to the west, thus reinforcing the major Fort of São Julião da Barra to the west. António Luís de Meneses, 1st Marquis of Marialva, was given responsibility for the work. en.wikipedia.org/wiki/Fort_of_São_Bruno

The Sintra National Palace, also known as Palácio da Vila, is one of Portugal's most iconic monuments and the oldest royal palace in the country. Located in the historic center of Sintra, it is easily recognizable by its two large, white, conical chimneys, nearly 33 meters high, visible from many points in the city.

It was originally a Hieronymite monastery founded in the 16th century, dedicated to Our Lady of Sorrow. After the 1755 earthquake, it fell into ruins and was acquired by King Ferdinand II in 1838. Between 1842 and 1854, it became a summer palace for the Portuguese royal family. In 1910, following the end of the monarchy, it passed into state hands and was opened to the public.

The Pena Palace in Sintra is one of Portugal's most spectacular monuments and a jewel of European Romanticism. Located high in the Sintra Mountains, about 25 km from Lisbon, this palace looks like something out of a fairy tale with its colorful and eclectic architecture.
