Daylight for strategic intervention in historic towns: the cases of Cairo and Edinburgh

There is a growing concern about the effects of intervention projects on heritage sites, in particular the way renewing building materials affect the sense of place. In one city, old Cairo, the implementation of renewals has instigated a cultural debate on whether the changes have negatively affected the identity of the area. Similarly, the 2005 management plan of the old town of Edinburgh has also indicated that one of the major challenges the site faces is the erosion of Edinburgh's unique sense of place and outstanding townscape through the loss of local materials, inappropriate intervention, and the introduction of inappropriate materials.
