Moorish Castle in Sintra, Portugal

The ruins of the Moorish castle in Sintra, a city registered as a World Heritage Site in Portugal. Sintra flourished as a summer resort for the royal family, and these are the ruins of a castle built on a mountain by the Moors, and you can walk along the castle walls. The view was great and it was a lot of fun. I've never been to the Great Wall of China, but I strolled along the walls, wondering if this is what the Great Wall of China was like. #WorldHeritage
