Castelo de Sao Jorge

Castelo de São Jorge crowns Lisbon's highest hill with medieval walls that frame the city's best panoramic views. You'll walk ancient ramparts (though they're largely 20th-century reconstructions after earthquake damage) while peacocks roam the gardens freely. The real draw is the Camera Obscura, a 360-degree live projection of Lisbon that updates in real-time, plus views stretching from the Tagus River to the red rooftops of Alfama below.

The visit flows naturally from the entrance gates through terraced gardens where peacocks strut between olive trees and archaeological ruins. You'll climb stone steps along the fortress walls, stopping at multiple viewpoints that reveal different angles of the city. The Camera Obscura tour runs every 20 minutes in a small darkened room where mirrors project a bird's-eye view of Lisbon onto a white dish.

At EUR 15, you're paying premium prices for walls and views, but those views genuinely justify the cost. Skip the small museum inside (it's forgettable) and focus your time walking the complete rampart circuit. The archaeological site adds some context, but most people come for Instagram shots and leave satisfied. The steep climb through Alfama to reach the entrance is half the experience.
