São Jorge Castle (Portuguese: Castelo de São Jorge; Portuguese pronunciation: [kɐʃˈtɛlu dɨ sɐ̃w̃ ˈʒɔɾʒ(ɨ)]; English: Saint George Castle) is a historic castle in the Portuguese capital of Lisbon, located in the freguesia of Santa Maria Maior. Human occupation of the castle hill dates to at least the 8th century BC[1][2] while the first fortifications built date from the 1st century BC.[3] The hill on which São Jorge Castle stands has played an important part in the history of Lisbon, having served as the location of fortifications occupied successively by Phoenicians, Carthaginians, Romans, and Moors, before its conquest by the Portuguese in the 1147 Siege of Lisbon. Since the 12th century, the castle has variously served as a royal palace, a military barracks, home of the Torre do Tombo National Archive, and now as a national monument and museum.

It was classified a UNESCO World Heritage Site, along with the nearby Tower of Belém, in 1983.

The Alfama (Portuguese pronunciation: [aɫˈfɐmɐ]) is the oldest neighborhood of Lisbon, spreading on the slope between the São Jorge Castle and the Tagus river.

The district includes the freguesias (parishes) of São Miguel, Santo Estêvão, São Vicente de Fora and part of the two streets, "Freguesia da Sé: Rua do Barão" and "Rua São João da Praça".

The 25 de Abril Bridge (Portuguese: Ponte 25 de Abril, 25th of April Bridge, Portuguese pronunciation: [ˈpõt(ɨ) ˈvĩt i ˈsĩku ðɨ ɐˈβɾiɫ]) is a suspension bridge connecting the city of Lisbon, capital of Portugal, to the municipality of Almada on the left (south) bank of the Tagus river. It was inaugurated on August 6, 1966. It is often compared to the Golden Gate Bridge in San Francisco, US, because they are both suspension bridges of similar color. It was built by the American Bridge Company which constructed the San Francisco–Oakland Bay Bridge, but not the Golden Gate. With a total length of 2,277 metres (7,470 ft), it is the 40th largest suspension bridge in the world. The upper deck carries six car lanes, while the lower deck carries a double track railway electrified at 25 kV AC; the train platform was added in 1999. After the Carnation Revolution which overthrew the remnants of Salazar's dictatorship, the bridge was renamed for April 25, the date of the revolution.

Belém Tower (Portuguese: Torre de Belém, pronounced [ˈtoʁ(ɨ) dɨ bɨˈlɐ̃ȷ̃]), officially the Tower of Saint Vincent (Portuguese: Torre de São Vicente) is a 16th-century fortification located in Lisbon that served as a point of embarkation and disembarkation for Portuguese explorers and as a ceremonial gateway to Lisbon.[1][2] It was built during the height of the Portuguese Renaissance, and is a prominent example of the Portuguese Manueline style,[3] but it also incorporates hints of other architectural styles.[4] The structure was built from lioz limestone and is composed of a bastion and a 30-metre (98.4 ft),[5] four-storey tower. Since 1983, the tower has been a UNESCO World Heritage Site, along with the Jerónimos Monastery. It is often portrayed as a symbol of Europe's Age of Discoveries[2] and as a metonym for Portugal or Lisbon, given its landmark status. In fact, the tower was built on a small island in the Tagus river near the Lisbon shore.[4][6]
