Eco-construction commitment

Our work is carried out in an eco-construction approach using the ancient know-how of building:

  • Waterproofing screed in crushed brick 
  • Insulating screed with clay balls
  • Insulating plaster made of lime and hemp 
  • Laying of locally made terracotta tiles 
  • Sifting of our rubble for reuse
  • Conservation of old stones for reuse
  • Purchase of French wood from certified sustainable forests 
  • Manufacture of wooden joinery in our premises and natural treatment of wood;
  • Manufacture of ironworks in our premises;
  • Purchase of lime, sand and stone from local sources;
  • Use of natural ochres for our coatings.

And modern eco-construction techniques:

  • Installation of floor heating/cooling systems powered by heat pumps;
  • Use of cellular glass floor insulation and thermal break (produced with over 60% recycled content);
  • Installation of low energy LED lighting;
  • Installation of insulated, double-glazed, wooden windows


The Fort d’Entrecasteaux (upper part of the Fort Saint-Nicolas), classified as a historical monument since 1969, is the flagship of ACTA VISTA’s integration and vocational training workcamps. Owned by the French Army until 2011, the first restoration projects were ordered by the City of Marseille from 2003 on the glacis at the foot of the ramparts (areas then owned by the City of Marseille), then on the entire site from 2011, when the City of Marseille acquired Fort Entrecasteaux. 

This imposing integration and personal training site allows the establishment and development of an innovative and committed social project in the heart of Marseille, for the inhabitants of the region. 

98 jobs are contracted per year on this site, with permanent entries and exits. Each year, this site enables the training of more than 230 job seekers from the region in the trades of old buildings.
