The Underground Railroad was a network of secret routes and safe houses established in the United States during the early to mid-19th century, and used by African-American slaves to escape into free states and Canada with the aid of abolitionists and allies who were sympathetic to their cause. It worked by having African American Slaves move from safe house to safe house, like stops on a railroad. These people would eventually make their way north to seek freedom.

Answer:
The Leaning Tower of Pisa is a building in Pisa, Italy. It is a bell tower. It is famous because it is not vertical. The tower was once leaning more and more to the ground, but recently much restoration work has been done to stop it from falling over completely. There was scaffolding all around the tower for 20 years. On 26 April 2011, the last bit of scaffolding was removed so that the tower can be seen properly again.
The height of the tower is about 56 metres from the ground. Its weight is about 14,500 tonnes. It now leans at about 3.99 degrees. The tower has 294 steps.
When the second floor was built in 1178, the tower started to lean. This was because it had a small three-meter foundation in soft soil. The design of this tower was bad from the beginning. Construction was stopped for almost 100 years because the people of Pisa were often at war with Genoa, Lucca, and Florence.
Like the Roman Colosseum, the Leaning Tower of Pisa is one of the seven wonders of the medieval world that is located in Italy.
