The Moorish Castle, of the ‘The Castelo dos Mouros’ is an ancient world heritage site, found in the hilltops of Sintra, just an hour outside of Lisbon. The secret garden of the Portuguese countryside. It was first built in the 9th century but fell into ruins after its final abandonment in the 18th century. When King Ferdinand built his fairytale castle just down the road, he also took it upon himself to retake these ruins for the people of Portugal so that this magnificent piece of history may be preserved for years to come. To this day, it is one of the most amazing places to visit when coming to Sintra. Most people visit this site as a part of a Day Trip to Sintra, but if you’re into history and hiking, you can easily make an entire day out of touring this site and exploring around the surrounding areas.
