The National Palace of Sintra, also known as Palácio da Vila, was one of the palaces used by the Portuguese Royal Family practically until the end of the Monarchy in 1910.

Of urban implantation, its construction began in the fifteenth century, with an unknown author's trait. It features features medieval, Gothic, Manueline, Renaissance and romantic architecture. It is considered an example of organic architecture, of apparently separate body set, but which are part of a whole articulated with each other, through courtyards, stairs, corridors and galleries. It has the largest set of Mudejar tiles in the country.

It is dominated by two large semi-sized chimneys that crown the kitchen and constitute the "ex-libris" of Sintra.

This small waterfall, is very close to Quinta da Regaleira, and interrupts a line of high walls that line the road. The green of the scenery and the sound of running water makes that place unique. Another of the natural beauties that Sintra offers to those who visit it. 

The Regaleira Palace is the largest building in and common name given to Quinta da Regaleira. Also known as "Palace of the Monteiro Millionaire", a reference to the surname of its former owner, António Augusto Carvalho Monteiro.

The house is located on the hillside, a short distance from Sintra’s Historic Centre, and classified as Property in the Public Interest since 2002.

With the aid of Italian architect Luigi Manini, Carvalho Monteiro transformed the 4 hectare estate into a palace surrounded by lush gardens, lakes, caves, and enigmatic constructions, places that hide alchemical meanings such as those evoked by Freemasonry, the Templars, and the Rose-cross. He shapes the space with mixed lines, evoking Romanesque, Gothic, Renaissance and Manueline architecture.

Quinta da Regaleira must be experienced. It is not enough to hear about its memory, landscape and mysteries. You must get to know the estate, contemplate the scenery among the gardens and constructions, admire the Palace, a true philosophical mansion of alchemical inspiration, and walk through the exotic park and feel its spirit.

Sintra is one of those places with a magical atmosphere. High in the hills on a strategic location it was conquered by Moors and Christians.  Lord Byron called it Glorious Sintra.

In the historic center of the romantic village of Sintra, Portugal, there remain many buildings and vestiges of various eras and cultural movements. It circumscribes a comprehensive area of diverse heritage, including palaces, castles, farms and parks with different classifications. From municipal heritage to world heritage, duly classified by UNESCO.
