The history of the city of Lefkada, the capital of the insular complex that constitutes the homonymous county, although goes back to the medieval age, is even today barely known and even less documented. The historic structure of its urban web and the physiognomy of its houses have also been studied inadequately. For this reason every damage of its densely built historic center destroys elements of its past and history and turns out to be fatal for the documentation of the evolution of the only preserved suburb, from the originally three, of the medieval capital of the island. The rapidly developing building activity and the replacement of the traditional by modern building materials has unfortunately dishonoured the historic identity of the characteristic anti-seismic architecture and the urban profile of the city and has reversed the balance between authentic and false architectural work at the expense of the former.
