Castelo de São Jorge (St. George's Castle) in Lisbon is absolutely worth it if your primary goal is to see the best panoramic views of the city, but it may feel underwhelming if you are expecting a furnished palace. In 2026, the castle remains one of Lisbon's most popular attractions, primarily for its walkable 11th-century Moorish walls and its commanding position over the Alfama district and the Tagus River. The entrance fee (approx. €15) covers access to the ramparts, the archaeological site, and a small museum. A major highlight is the Camera Obscura, which provides a 360-degree real-time view of the city. However, if you are short on time or budget, many travelers find that the "miradouros" (free viewpoints) scattered around Lisbon provide similar vistas for free. The castle is "worth it" for history buffs and families who enjoy exploring fortress ruins and seeing the resident peacocks, but for the best experience, it is highly recommended to visit at sunset when the stone walls and the city below are bathed in a spectacular golden light.
