Consisting of various bodies built during the course of successive epochs on the so-called "Chão da Oliva", the Paço da Vila de Sintra is one of the most important examples of regal architecture in Portugal and for that reason is classified as a National Monument. This gradual multiplication of buildings, with different styles, is largely responsible for the enigmatic enchantment of this ancient palace, dominated by outstanding  twin chimneys atop the kitchen.

After the Reconquest, the Palace passed into the possession of the Crown and was considerably enlarged, not only in the reign of D. Dinis - who in 1281 laid down that the conservation of the Palace should be entrusted to the enfranchised Moors of Colares -but especially in the reigns of Dom João I (1385-1433) and D. Manuel (1495-1521).

And also, apart from the elements of Gothic, Mudejar, Manueline and Renaissance architecture, are the wonderful azulejos (coloured glazed tiles) from the 15th and 16th Centuries in various halls, terraces and in the Royal Chapel.
