AHI Architectural Heritage Intervention

“Contributing to enhancing our heritage, as the way forward for 21 st Century architecture is our raison d’être; to emphasize a diverse, rich vision that necessarily complements the intervention is our mission, and achieving it with reflexive and purposeful efforts is the challenge”.

This project, founded in, and directed since, 2011 by Ramon Calonge, Oriol Cusidó, Marc Manzano and Jordi Portal, architects and members of the Group of Architects for the Defence and Intervention in Architectural Heritage (AADIPA), has, through the years become a platform that includes four actions that are both independent and transversal.
The European Award, a biennial event that brings together and showcases the multiple approaches of intervention in Europe.

The International Biennial, a framework that serves to compare and gain closer insight of quality interventions in architectural heritage in non-European countries.

The digital Archive, a live and open window that provides a panoramic view of interventions in the history of our surroundings.

The Forum, a meeting place where you can participate in on-going debates about the main preoccupations and lines of thought about interventions in architectural heritage in Europe.

The formerly biggest iron foundry in Europe (before 1920) was closed in the early 1980s. Most of the manufacturing equipment was sold abroad. Only the twelve-meter-high and 240-meter-long ore and coal bunker and the switching house were preserved as monuments. In addition, a number of relicts of the production process as ruins. These structures develop, due to the long fallow times on the site into a piece of second-hand nature. For long-term urban development, a series of open spaces have been proposed. The bunker is released and staged as a spectacular solitaire. The western part offers a view from there insights into the imposing underworld of the plant. An asphalt surface marks a space in front of the bunker, as a sports and exercise area. The foundation ruins of the former blast furnaces are partially integrated into a skating facility. Further east, they are located in an extensive meadow area and are designed as climbing objects. The plateau between the wall remains of the foundry hall was designed as an extensive cross-bike course.
