The speaker, Ruhi Ceneti, introduces the world's largest underground city, which was discovered during a renovation in the early 1960s. The city, located in Turkey, was used by Christians to hide from persecution during the Roman Empire. It was built using volcanic formations and was designed to be a self-sufficient community with various facilities like shelter rooms, food warehouses, churches, and even burial chambers. The city was closed during restoration and can hold up to 21 people. The city's ventilation system, a 55-meter deep shaft connected to the earth, was used as a water well and for oxygen supply. The city's construction was a significant feat, requiring thousands of workers and the removal of more than 5 million tons of rocks and soil. The city was used as a missionary school and a place to practice Christianity. The city was also connected to other underground cities, forming a network of underground cities. The city was closed during the restoration and is now open for tourists. The speaker emphasizes the importance of respecting the historical significance of the city and the need to preserve it for future generations.
