Way up there, on the highest of the seven hills, we visited Castelo de São Jorge. Saint George Castle is a Moorish castle occupying a commanding hilltop overlooking the historic centre of the Portuguese city of Lisbon and Tagus River (Wikipedia). The walk up there is somehow worth it. The view is more than awesome. The castle, IMHO, is rather unattractive. It’s been restored (a couple of times, I think). It’s basically two courts and a wall. But what a view!
