Saint Gobin, FRANCE
The mirrors in Versailles castle were made in the small northern town of Saint Gobin in the late 17th century. The site of the old royal glassworks is now a group of neglected buildings from different eras. Over the centuries, Saint Gobin became a huge multinational company that sells building materials. Today it is present in 67 countries and employs over 170,000 people but there is no sign of it here.
