As part of a government-led renovation project, Studio Roosegaarde created three sustainably lit art installations to highlight the historic dike’s importance to The Netherlands. Designed to help protect the country from floods, the Afsluitdijk dike is 32 kilometers long and an international icon of design. The art project, called Icoon Afsluitdijk, has three elements: Gates of Light, Windvogel and Glowing Nature.
