The Castelo de Sao Jorge is a castle in Alfama (Lisbon) which is integrated in the city. We visited the castle as a students group and we had about one hour to go around which is a little bit short because it is not a small castle.
From the highest walls you have a brilliant view over nearly every part of Lisbon. Some places are without a balustrade and that might make you a little bit uneasy if you have to walk there.
If you plan to visit the castle, take suncream, a camera (you wouldn't want to miss the view) and sturdy footwear! And take you're time!
