A House of Terror is a real-life place where people were held against their will and made to suffer cruel and horrible acts. In many cases, these houses were used by dictators or other governments to torture people to keep them from spreading their beliefs or messages. People were often taken from their homes, separated from their families, and put in these houses where they were physically and emotionally abused. They were often not given enough food or water, and some were even killed. It's a terrible thing to think about, and it's important to remember that it happened.
