Virtual Cities as Memoryscapes

The digital re-creation of a past city represents more than a mere depiction of its historical awareness; it also represents its imaginability. In retrospect, the imaginability of the city corresponds to the outcome of various perceptions that we have acquired of it over time, and which currently confers us with a certain degree of accuracy in its readability. The imaginability of the city is therefore a determining factor in virtually re-creating the latter and subsequently converting it into a memoryscape. This theory can be validated by the specific case study of Lisbon, Portugal, which has during the last few years been the subject of at least four projects that sought to virtually re-create the city’s past. Despite presenting themselves distinctively with different technological applications, the four projects held the same starting point; the great Lisbon earthquake of 1755 (a major disruptive event in its history), and were all focused on presenting the cityscape that was lost as a result. Lisbon’s iconography from the sixteenth century to the mid-eighteenth century (drawings, engravings, and paintings) was used as crucial data.
