English: Architects from the U.S. National Park Service's Historic American Building Survey (HABS) embarked on a ground-breaking project to fully document the towers. Using high definition surveying, also known as laser scanning, Dana Lockett and Paul Davidson captured the elaborate terracotta details of each façade as well as the brickwork of their exposed foundations to a level of accuracy never previously achieved. Their work, sponsored by the U.S. Department of State's Cultural Heritage Center, is an effort to help cultural heritage professionals in Afghanistan preserve the towers by providing baseline documentation that will underpin future conservation and preservation activities.
