Perched atop Lisbon's highest hill, the Castelo de S. Jorge watches over the city like an old guardian still wary of approaching ships. 

This Moorish castle, with its turrets and ramparts, offers a tangible link to Lisbon's storied past, where whispers of ancient battles mingle with the laughter of tourists. The castle grounds are not just a historical site; they're a panoramic viewpoint where Lisbon spreads out in a mosaic of life below. Strolling through its courtyards and gardens, you might just feel the echoes of history underfoot, urging you to explore every nook and cranny of this commanding fortress.
