The main building in Jurassic Park is the Visitor Center. It is a large, rectangular building that houses the park's control room, labs, offices, and living quarters. The Visitor Center is the nerve center of Jurassic Park. It is where the park's staff monitors the animals, runs experiments, and makes decisions about the park. The Visitor Center is also where the park's guests stay. The building has a large lobby, a restaurant, and a gift shop. The Visitor Center is the only building in Jurassic Park that is not made out of concrete.
