Castelo dos Mouros, as it is called in Portugal was about half hour north of Lisboa, just outside of Sintra. It is a popular tourist destination, full of history about this area of Portugal. This site was once an important military fortification and speaks of the Islamic presence in this region. It was probably built between the 8th and 9th centuries. Overlooking Sintra, it acted as a watchtower to protect Lisbon and the surrounding area. It was a pretty windy day the day we visited. We actually visited several places on this day. The Frys and the Feehans were not letting any place go undiscovered! Though, the Frys had already been there several times while they lived in Portugal, it was fun just to see it together and of course click pictures.
