ABSTRACT

The issues addressed in the restoration project for Zenobito’s Tower, in Capraia island, are a stimulus for a broader debate on sustainability of architectural conservation interventions in delicate environmental contexts inside protected areas. As a matter of fact the conservation intervention on the tower and the absolute preservation of the environmental context impose a severity rarely practiced, even for restoration. The tower is three and half hours walking distance from the village, in a wilderness area where in some periods even walking is forbidden, due to protection of nesting birds. The sea in front of it is a marine protected reserve, with severe limits on access by boat.

All this led to a serious reflection and a careful evaluation of every factor that may have an impact on the environment while installing a restoration yard in such a context

1 ) preliminary stage to the construction site itself

2 ) installation of the yard and its removal, including transport issues

3) post-construction monitoring and maintenance phase of the intervention

The following goals were defined: a) "physical preservation" of the tower, b) minimal intervention, c) usage of eco-friendly materials.

This paper continues with a theoretical discussion that puts several questions and suggests guidelines that should be valid in all similar situations.
