Résumé en anglais
The conservation of protected urban areas (large and small,including cities, towns and historical centres or quarters) is affected by
various factors that mitigate the authenticity and integrity of this culturalheritage. Within this universe, small-scale phenomena that, in the majority of
cases, occur practically undetected, gradually contribute towards alterationof the appearance and content of the architectural setting of these localities.
This work concentrates on analysis of the cumulative effect of minoralterations carried out gradually by the users of these areas, a topic that has
been attracting particular attention from the specialists and entitiesconcerned with conservation. Such nibbling modifications are defined as
"inch-by-inch deterioration."At the outset, the article discusses the conception of protected urban areas. It
then proceeds to seek understanding of the present conditions of such spaces,through analyses of their transformation, and the conservation measures
adopted. Finally, it focuses on a study of the nature, causes andconsequences of this creeping alteration, in particular, how they undermine
the ‘spirit of place’ of these areas, as well as how they could be reversedwith special reference to Rio de Janeiro city’s protected quarters.
