Since its origin as a Roman crossroads, Luxembourg has developed as a multicultural society. Today, 32 percent of the Grand Duchy's 400,000 residents are foreigners, and its Deutsch and Franco cultural influences are reflected in the native L?tzebuergesch language, which has Germanic roots while encorporating many French words. About 51 miles long and 36 miles wide, Luxembourg's geography is divided in two. The hilly Ardennes region to the north is where the Battle of the Bulge was fought during World War II. To the south is "Gutland," typified by rolling farmlands and woods. Around 85,000 people live in Luxembourg city. Its architecture tells a history of foreign invasions -- Spanish turrets are juxtaposed with Art Nouveau, and skyscrapers built by legions of international bankers now occupy the city.
