Willful Destruction: You Can Fight Back

We are at a turning point in history. We must act now to save our irreplaceable cultural heritage.

These are barrel bombs set up by ISIL forces in Nimrud, Northwest Palace, Iraq, in front of a wall of ancient bas-relief panels.

The bombs were detonated. Now nothing but rubble remains of these priceless relief sculptures telling the stories of ancient Syria. The horror of today’s organized, willful destruction cries out to us to save what still remains of our imperiled cultural treasures.

Your support will help CHI transfer essential knowledge and skills to the brave cultural heritage caretakers in the Middle East and North Africa.

CHI democratizes technology and is partnering with local heritage workers.

We train local cultural caretakers in how to apply scientific methods for creating and archiving measurable 3D data, using off-the-shelf cameras. A single caretaker with a digital camera and the knowledge of where to stand and point it could have documented the destroyed Nimrud bas-reliefs in precise, submillimeter 3D in less than a day.

CHI’s low-cost techniques and gear are designed to scale to meet the worldwide challenge.

For 14 years, CHI has collaborated with worldwide experts to develop accessible tools and techniques for cultural heritage preservation. The techniques and equipment we foster are user-friendly, accessible, and inexpensive enough to ease their adoption by local cultural caretakers anywhere.

Today CHI is collaborating with the American Schools of Oriental Research (ASOR) and the American Archaeological Mission to Libya to train heritage workers where they are most needed. Those trainees can then teach others, and the knowledge spreads.
