1. In most ways, the English city of Liverpool is no different from other large cities. It is full of people, restaurants, museums, and shops. However, Liverpool stands out in one interesting way. Under the busy streets, there are miles of old tunnels. For many years, the tunnels were nearly forgotten. There was no evidence that the tunnels were real. In 2001, a small group of curious people were delighted to discover that the old tales were true. A huge network of tunnels snaked under the city.
2. We now know that the tunnels were built sometime in the early 1800s. A man named Joseph Williamson designed them. But there is a lot we still don't know. Why did Williamson want the tunnels? Were they ever used? If so, for what? We can only guess.
3. One idea is that Williamson, who was rich, was trying to help others. Many people were jobless at that time, and Williamson was known to be kind. Perhaps he came up with the tunnel project so that he could offer people jobs. Another guess is that Williamson used the tunnels for secret business. The tunnels would have made it possible for him to go places without being seen.
4. Still others suspect that Williamson built the tunnels for safety reasons. Perhaps he was afraid that some type of dangerous event would happen. The tunnels would have offered protection for himself and his loved ones.
5. Some people who study the tunnels have yet another idea. They believed that long ago, people removed sandstone from the land. The sandstone removal would have left huge holes. Williamson may have wanted to fix the holes. Instead of filling them, perhaps he had his workers build archways (拱道) across them. In time, houses and other constructions were built over the archways.
