Modern heritage conservation practices at Khami World Heritage site in Zimbabwe reveal a tension between indigenous beliefs and Western restoration principles. While post-colonial restorations, particularly drystone wall repairs between 2000 and 2015, preserved the site's structural integrity to avoid delisting, they disrupted local traditions that viewed Khami as a sacred resting place for ancestors with minimal human intervention. The study highlights how these compromises—balancing international conservation standards with local spiritual significance—sustain Khami's economic value as a tourist destination while acknowledging their limitations in fully aligning with indigenous practices.

The study identifies a dedicated pottery kiln and manufacturing area, shedding light on the organization of this craft and its role in the monastery's economy. Clay rods found at the site suggest specialized production techniques and raise questions about the users and economic significance of these findings. This research contributes to understanding the broader economic context of medieval Serbian monasteries.
