Terra 2021


We are monitoring the rapidly evolving COVID-19 pandemic and the challenges it poses.
With the timing of Terra 2021 still over a year away, we are continuing to move forward with planning in the anticipation that it can happen as scheduled.
We will keep you updated of possible changes as we have more information to share with you.

Please stay safe and well.


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.

The congress will be held at the Santa Fe Community Convention Center in Santa Fe, New Mexico. The recently built convention facility is designed to echo the adobe structures characteristic of New Mexico, and features state-of-the-art audio/visual capabilities and high-speed Wi-Fi throughout the building. The convention center is located in close proximity to numerous hotels, shops and restaurants.


Three Santa Fe hotels close to the convention center will be proposed as the official congress hotels with a preferred rate in the next announcement. Other smaller or less expensive hotels will also be listed for those who prefer more independent accommodations. Participants will be responsible for making their own payments directly to all hotels.

Congress Visits

The congress program will include one half-day dedicated to site visits in and around Santa Fe, as well as auxiliary exhibits and activities on the theme of earthen architecture organized for the public.

Funding Opportunities

Limited sources of funding may be available for participants who need financial assistance to attend the congress. Participants must indicate a need for funding with their registration.

Optional pre-congress workshops and post-congress tours

In conjunction with Terra 2021, optional pre-congress workshops and post-congress tours will be organized at an additional cost to the congress registration.

Pre-congress workshop
Optional pre-congress workshops will be one to three days depending on the nature of the topics covered. They will provide the opportunity for registered participants to acquire hands-on skills and technical training. Pre-congress workshops will be offered within the period of June 5 – 7, 2021.

Post-congress tours
Optional post – congress tours will be offered for participants to experience the archaeological, historic and contemporary earthen heritage in and around Santa Fe and neighboring states. Experienced guides, staff from the National Park Service and University of New Mexico, and other professionals will lead and assist on the tours. The post-congress tours are planned for one to four days and will be offered within the period of June 12 – 15, 2021.

Detailed itineraries, costs, and registration information for the pre-congress workshops and the post-congress tours will be provided in the next Terra 2021 announcement, scheduled to be posted online in June 2020.
