Iran finalized cultural preservation documents to secure a major global heritage designation for its ancient wind-catching technologies. Deputy Cultural Heritage Minister Ali Darabi announced advanced cross-provincial coordination during a strategic assembly in Mashhad on Saturday.
Three eastern provincial governments are unifying their administrative assets to complete the comprehensive preservation file. The targeted locations include key heritage zones within South Khorasan, Khorasan Razavi, and Sistan-Baluchestan. Therefore, regional administrators must establish uniform standards to protect these ancient distributed architectural systems permanently.
Experts identify these millennium-old Iranian historical windmills as pioneering examples of early industrial mechanics worldwide. Historians track the dissemination of this unique vertical-axis design from Persia to East Asia and Europe. Furthermore, technology researcher Robert Forbes documented how these structures powered essential agricultural processing activities for centuries.
The national government declared these unique mill structures as protected local heritage properties in 2002. Currently, researchers record approximately 1400 surviving mill structures scattered throughout the eastern desert territories. South Khorasan functions as the primary geographic center because the province contains over 310 intact facilities.
Builders constructed each tower using local organic clay materials, agricultural straw, and heavy wood supports. Each standard unit utilizes eight interior chambers containing six wooden vertical blades to trap powerful seasonal winds. Then, incoming air currents rapidly rotate these central blades to power heavy subterranean grain milling stones.
Federal departments view this joint registration project as an essential strategy to boost international tourism. Officials plan to finalize the remaining documentation before submitting the collective portfolio to global evaluators. Meanwhile, local preservationists continue restoring vulnerable clay walls to maintain structurally sound facilities across all regions.
