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.


Zollverein Park

Zollverein Park

With its status as UNESCO World Heritage site, Zollverein has a high radiance and attraction for the city of Essen and the Ruhr region. In the foreground is the impressive industrial architecture of the mine plant. The open spaces have an unobtrusive look which creates a surface to take an appropriate effect on the architecture; they complement the ensemble to a formal framework that makes the dimensions of the site tangible. The park has developed on industrially embossed terrain and does not deny its origins. It keeps its unique selling point by the high-contrast interacting between the clear forms and structures of industrial architecture and the variety of spontaneous vegetation. The shape and outer appearance of Zollverein Park are being developed by systematic and continuous maintenance. Zollverein Park is an exceptional open space. It offers a unique experience with its complex structures in conjunction with the mining facility. It attracts tourists and local residents equally. The visitor is invited to individually discover the park.
