Arquitectura Catalana .Cat is a dynamic initiative led by the Col·legi d'Arquitectes de Catalunya (COAC) aimed at enhancing awareness and accessibility of Catalonia's architectural heritage. The project boasts an extensive digital repository that focuses on modern and contemporary architecture developed from 1832 to the present day. This comprehensive collection is enriched by contributions from architectural firms, photographers, and various editorial projects, offering invaluable resources to both professionals and the general public.

Users can explore over 5,000 architectural works, along with detailed profiles of 2,170 authors and 216 photographers. The platform also features geolocated itineraries, allowing visitors to experience architecture firsthand through informative routes traversable by foot, bicycle, or car. With a commitment to continuous improvement, Arquitectura Catalana .Cat serves as a vital tool in the documentation and promotion of Catalonia's architectural landscape, solidifying its role as an international reference point for architectural knowledge.
