The project for the Civic Museums of Santa Caterina di Treviso was carried out in three different phases with a general aim: to regenerate a large part of the complex and to adapt it to high level exhibition, with safety and air conditioning standards, to create spaces for contemporary exhibitions. The project has touched on many aspects: to work out on structural problems, to clarify the functional areas, to redefine the interior paths and to create spaces dedicated to international events.
