Embarrassing, really, that the UN agency responsible for preserving world culture should have let its own shoplace headquarters crumble. Now a long-overdue restoration. “In recent years, large mesh nets have been hung from the façade of UNESCO’s main building to catch falling chunks of concrete. Roofs leaked and water damage plagued the basement where archives are stored. The neglected state of the UNESCO complex seems particularly paradoxical given the agency’s role as a guardian of the world’s cultural heritage. Since 2000, UNESCO has embarked on a campaign to add Modernist monuments to its World Heritage List, which obligates U.N. member states to care for sites in their territories.”
