Also, noteworthy are the hermitage of Saint Saturnino and the romantic-revivalist mansion from 1918.

The building consists of two sections with sober and well-proportioned lines, already revealing a neoclassical taste. In 1802, the two lateral sections were linked by a large triumphal arch, commemorating the visit of D. João IV. Inside, the highlight is a room with mural paintings, of the Pillement type, and the Convention Room, with maritime and mythological scenes. It was transformed into a hotel, but maintains its original design.

This 19th-century building is topped by bulbous domes and features revivalist, Moorish, and Neo-Gothic motifs decorating the friezes, windows, and entrances. Of particular note are the Neo-Mudéjar interior cladding and the profusion of intricate stucco work. The building is surrounded by elegant romantic gardens.

This building originated from the desire of King Pedro V to transform the Quinta de Queluz into a palace. Construction began in 1747 under the direction of Mateus Vicente de Oliveira and later J. B. Robillon, who gave the palace its exquisite decoration. Inside the palace, the throne room, the music room, and the ambassadors' room are prominent features. Its gardens are adorned with statues, lakes, and fountains. The grand canal has walls covered in tiles.

Also known as the Palace of Sintra, this impressive palatial example is the only surviving example of the great Royal Palaces of the Middle Ages. With a complex and irregular layout, this palace is the result of several construction campaigns, the main ones being from the reigns of King John I, King Manuel I, and the first third of the 16th century. The Palace of Sintra is the most ambitious Mudéjar art project in Portugal.

This estate, which belonged to the Barons of Regaleira, was built in the early 20th century. Designed by the Italian architect-set designer Luigi Manini, it was built in the Romantic style.

The estate presents itself as an impressive combination of styles and constructions (gardens, wells, towers, lakes, statues, caves) where an intimate yet theatrical feeling is maintained.

This castle was built in the 12th century and later underwent several modifications, mainly during the reign of King Ferdinand II. Its current appearance possibly dates from this period.

The Pena National Palace was built on the ruins of a Manueline-style convent and served as a summer residence for the monarchs. This work perfectly combines Neo-Gothic and Neo-Manueline elements with Muslim and Indian elements. This combination, along with the lush vegetation of the Pena park, accentuates its exotic and fantastical aspect. Inside, the ambiance of a royal residence is preserved.

Built amidst cliffs and vegetation, this convent is also known as the Convent of Santa Cruz da Serra or of Cork. A simple, rustic construction, it was founded in 1560 by D. Álvaro de Castro, fulfilling a vow he made to his father, D. João de Castro. Everything in this space is miniature: the cells, lined with cork, the refectory, and the small church with its marble altar, whose vault was carved from the rock itself. It is believed to have been abandoned in 1834, following the suppression of religious orders decreed by the liberal regime.
