Draped across seven hills, Lisbon was once the center of a vast maritime empire that stretched from the west coast of Africa to the Spice Islands of the East Indies. Then, on November 1, 1755, a violent earthquake destroyed two-thirds of the city in the space of 10 minutes. Only the Alfama, the old Moorish quarter, survived. Today, Lisbon is a stately city of Neoclassical buildings and wide plazas. Eternally linked to the sea, Lisbon's magnificent harbor is spanned by the longest suspension bridge in Europe.
