The Alfama is one of the oldest quarters in Lisboa. Since it largely survived the earthquake of 1755, the area still retains much of its original layout. Adjacent to the Alfama are the likewise old quarters of Castelo and Mouraria, on the western and northern slopes of the hill that is crowned by St. George's Castle.

The Graça quarter and the churches of São Vicente de Fora and Santa Engrácia are within walking distance of this area.

The Vasco da Gama Bridge spans the Tagus River near Lisbon, Portugal. When it opened (and still today) it is one of the longest in Europe. With a total length of 17 km including 0.8 km for the main bridge, 12.3 km in viaducts, and 4.8 km in dedicated access roads, this magnificent structure is an immense cable-stayed bridge. It is named after Vasco da Gama – the famous maritime explorer, which in 1498 discovered the sea route to the Indies around the Cape of Good Hope.
