13th World Congress on Earthen Architectural Heritage

ANNOUNCEMENT: Terra 2021 13th World Congress on Earthen Architectural Heritage will take place in Santa Fe, New Mexico, USA from June 8 – 11, 2021. This is the thirteenth international congress organized by the earthen architecture community under the aegis of ICOMOS since 1972, and the second to be held in New Mexico, thirty years after Adobe 90 in Las Cruces, New Mexico. Terra 2021 is expected to draw up to 600 specialists in the fields of conservation, anthropology, archaeology, architecture and engineering, scientific research, site management, and sustainable development of earthen architectural heritage. 

The four-day program will include presentations, posters and videos / digital media that reflect the latest research and best practice in the study and conservation of earthen heritage around the world. The wealth, variety and significance of earthen heritage in Santa Fe, New Mexico and the greater region of the southwestern United States and northern Mexico make it an ideal setting for the congress and will help inform and stimulate conversations around earthen heritage. The program will include sessions presenting technical information, management issues, methodology, advances in research, case studies and guidelines for best practice.

Organized by Getty Conservation Institute, National Park Service, Vanishing Treasures Program and University of Pennsylvania, Stuart Weitzman School of Design.
