    Many of the world's famous cities are known by some special names. Paris is known as the "City of Light". Hong Kong is the "Wall Street of Asia". One small city in Pennsylvania may be the sweetest place on Earth. That is town of Hershey, which is known as the "Chocolate Town". It is named after Milton Hershey, the founder of the largest chocolate factory in the world.

    Milton Hershey built his first candy factory in the early 1900s. At the time, Hershey was developing a technique for milk chocolate. Eventually he succeeded. Hershey was also the first to produce individually wrapped chocolate bars. His factory grew and produced more and more types of chocolate. To this day, Hershey's chocolate factory is the largest in the world. Hershey used his success to give back to the community. He built a town around the factory for his employees. He gave streets fun names like Chocolate Avenue. He built schools, parks and shops. This generous man gave millions of dollars to charity. He built an amusement park with rides, trains for children and a swimming pool. Over the years, the town grew. People from near and far came to visit this special town, whose beauty and fame continue to attract lots of tourists. Every year close to three million tourists visit the Chocolate Town.

    Today visitors to the city can enjoy a variety of attractions and activities. The Hershey chocolate factory offers tours. Visitors can learn all about chocolate and how it is made. A gift shop sells all kinds of chocolate and toys made to look like chocolate. Even if you don't buy a souvenir, there is one thing that is impossible to forget: the wonderful aroma of fresh chocolate everywhere. In this special place even the streetlights are shaped like chocolate.

    Another attraction is the Hershey Hotel. It has an unusual mineral spring where guests can enjoy a variety of special treatments. The treatments all have one thing in common: chocolate.
