The Cultural Landscape of Sintra is located in Portugal’s central region, at the extreme west of the Iberian Peninsula and a few kilometres away from the Atlantic Ocean. This Cultural Landscape is an exceptional mixture of natural and cultural sites within a distinct framework. Seen from a distance, it gives the impression of an essentially natural landscape that is distinct from its surroundings: a small chain of forested granite mountains rising over the hilly rural landscape. When seen from closer at hand, the Serra reveals a surprisingly rich cultural evidence spanning over several centuries of Portugal's history.

In the 19th century Sintra became the first centre of European Romantic architecture. Ferdinand II turned a ruined monastery into a castle where this new sensitivity was displayed in the use of Gothic, Egyptian, Moorish and Renaissance elements and in the creation of a park blending local and exotic species of trees. Other fine dwellings, built along the same lines in the surrounding serra created a unique combination of parks and gardens which influenced the development of landscape architecture throughout Europe.

This cultural landscape is an extraordinary and unique complex of parks, gardens, palaces, country houses, monasteries and castles, which create an architecture that harmonizes with the exotic and overgrown vegetation, creating micro-landscapes of exotic and luxuriant beauty.
