Both languages, as well as English, are used at the university in Luxembourg city. At Vianden, in the Ardennes, a Victor Hugo Museum and a folklore museum feature different facets of local culture. The Grand Ducal Institute has exhibits of art, archaeology, local history, literature, and science. About one fourth of the land is farmed. Cattle graze in the extensive meadows and pastures.
Agricultural products grown in the north include barley, wheat, oats, and potatoes.
Vineyards in the southeast, in the valley of the Moselle River, produce still and sparkling wines. The woodlands that cover about 35 percent of the total land area form the basis for a small lumber industry. Iron and steel production is Luxembourg's leading industry, but rubber tire, plastic, chemical, and machine industries have grown in importance. Pig iron, steel, and rolled steel products account for nearly half of the country's exports. Heat from the steel mills is used to generate thermal electric power.
