From early times, man has been interested in art. People have often worked together to collect and save the world’s art treasures.

Fine art treasures from many countries are kept in an art museum called the Louvre (卢浮宫) in Paris, France. The works of art have been collected by the people of France over many centuries.

The Louvre has not always been a museum. The first building was a fort (要塞)with high walls and a round tower. It had a moat (护城河) to keep out the enemies. Over the years, the number of buildings around the fort grew. By 1350,the fort was no longer needed and became a palace home for French kings and queens.

During times of peace, new treasures were brought in. During times of war, many treasures were stolen, and the buildings were damaged(毁损).

When Francis I became King of France in the year of 1515,he brought in artists from many countries, and one of them was Leonardo da Vinci from Italy, whose Mona Lisa is the best-known painting in the museum today.

In 1793, the Louvre became a public museum, just as it is now. It is a place where art treasures have been saved for everyone to enjoy.
