I am back from Portugal. A wonderful place.
Sintra is a lovely town, a must see in Portugal. Wikipedia: The town was already described in the 11th century by the Arab geographer Al-Bacr and later by the poets Luís de Camões and Lord Byron (Childe Harold's Pilgrimage - 1809). The Moors built the Castelo dos Mouros in the 8th or 9th century. When Afonso Henriques, with the aid of Crusaders, recaptured Sintra in 1147, much of the castle was destroyed. Only four square towers, the battlements, and the ruins of a Romanesque chapel survived.
