ABOUT: GTR-DVD-1100 - Around thirty kilometres from Lisbon is the small historic Portuguese town of Sintra where once the rise and fall of an entire kingdom took place. King João The First ordered construction of the Palácio Nacional De Sintra on the foundations of a Moorish construction that dated back to the 10th century. From the palace there's a beautiful view across the Vila Velha, Sintra's old town. The Palácio Nacional De Sintra consists of a variety of architectural styles that include Moorish, Gothic and Manuelistic design. 530 metres above sea level, on the summit of the Sintra Mountains, the spectacular Palácio Nacional De Pena overlooks the town. At first sight its towers resemble minarets, a symbol of a courageous and successful combination of numerous architectural traditions. Three kilometres from the castle is the oldest building in Sintra, the towers and walls of a Moorish castle, the Castelo Dos Mouros. The thousand year old ruins are famous for their breathtaking views that extend for several kilometres across the landscape and even as far as the Atlantic Ocean. In 1147, King Alfonso and his army conquered the old fortress. Sintra's gardens are the most beautiful in Europe and due to the region's unique climate, subtropical plants flourish in the fertile volcanic earth close to the Atlantic Ocean. Beneath the southern sun, Sintra's historic architecture continues to blend harmoniously with the glorious splendour of Nature.
