Sintra (Portuguese pronunciation: [ˈsĩtɾɐ]) is a town in Sintra Municipality in Portugal, located in the Grande Lisboa subregion and the Lisbon Region. The town is a UNESCO World Heritage Site on account of its 19th century Romantic architecture. It has a population of c. 33,000 inhabitants.
Sintra has become a major tourist attraction, with many day-trippers visiting from nearby Lisbon. Attractions include the fabulous Pena Palace (19th c.) and the castle Castelo dos Mouros (8th or 9th century, reconstructed in the 19th century) with a breath-taking view of the Sintra-Cascais Natural Park, and the summer residence of the kings of Portugal Palácio Nacional de Sintra (largely 15th/16th century), in the town itself. The Sintra Mountain Range, one of the largest parks in the Lisbon area, (Serra de Sintra) is also a major tourist attraction. (From Wikipedia)
