Sintra's Pena Palace and Monserrate had a major effect on the development of European Romantic architecture in the 19th century. Its interest, however, is by no means limited to one or two important buildings, but is represented in the diversity of its palaces and parks, elegant manor houses, with their gardens and forests; mansions and chalets surrounded by a dense vegetation; long sections of walls winding around the highest of the peaks of the Serra, reminding us of centuries past; convents conducive to meditation, surrounded by mossy cliffs and murmuring fountains; austere churches and chapels, as well as smaller, more humble chapels, several of which comprise secular areas as Faith and Art and finally, archaeological remains which are often thousands of years old and which take us back to our deepest roots.
