Lisbon is a beautiful city and the old fortress Castelo de Sao Jorge is a great place to see it from. It sits on the hill above the city with 360 views. It’s a good place to start your tour of the city and a stoll through the old town at the foot of the castel or a ride in the historic tram should be part of your trip.
