All cities, even the newly built, have histories. Some have survived wars, bore witness to major historical events, or been burnt down and rebuilt. Lisbon, for instance, was hit by a devastating earthquake in 1755, which prompted a large-scale reconstruction and redesigning of the city. The changes made by its urban planners, which is largely the Lisbon we know today, are examples of how a city’s appearance can reflect their histories. The history of a city exists as a segment on a spectrum of time. If a city is destroyed and rebuilt, is it still the same city?
