Venice, a small, waterside city in northeast Italy, boils with happiness and excitement once every year.[22]Between February 21 and March 4, carnival hits the streets.
    For most people, carnival means large parties and feasting. But[23]in Venice, it also means traditional masks and clothes. These costumes were first meant to hide personal identities. Then, different social classes could mix in a sea of happiness.
    Bars and cafes are filled with partygoers who come to show off their beautiful clothes. Their desig is and creations are made by special studios. Ready-made costumes are not acceptable. "In the months before the carnival we work overtime to meet the demand," said a mask-maker. ""Many kilometres of silk and lace are made into costumes. For shopkeepers, carnival is the best time of year."
    The Venice carnival dates back to the Middle Ages. At that time, the city was one of the wealthiest in Europe. The tradition of celebrating with masks and costumes is thought to have been started by the "Stocking Companies". These were groups of young men who organized parties and festivals and wore colorful stockings to distinguish themselves. By the 18th century, the carnival had reached its height.[25]It all came to an end when Napoleon controlled Venice in 1797. But in 1979, local people brought the old traditions back to life.
    Now the Venice carnival attracts huge crowds from all over the world. This year, about 700,000 people are taking part. Hotels were fully booked months in advance, and bars and restaurants overflow every day.
