This file photo from a collection published by IRNA on October 11, 2017 shows people viewing a land artwork created with local minerals on the beach of the southern Iranian island of Hormoz in the Persian Gulf. Veteran land artist Ahmad Nadalian established the Persian Gulf Land Artists House on the island in 2010 to teach the locals how to conserve their environment, which was being threatened by misuse of the colorful minerals of Hormoz.
