From the vast subterranean networks of Cappadocia to the secret passages of Naours in France, these cities beneath the ground continue to captivate historians and travelers alike.
Derinkuyu: Cappadocia’s Hidden Marvel
Derinkuyu, located in Turkey’s Cappadocia region, is one of the largest and deepest underground cities ever discovered. Built thousands of years ago, this city stretches 18 stories below ground and could house up to 20,000 people, along with livestock and supplies. The city served as a refuge during times of war and persecution, particularly for early Christians escaping Roman soldiers. A 2024 report by UNESCO confirmed that Derinkuyu’s intricate ventilation systems and water wells showcased advanced engineering for its time. Today, it is one of Turkey’s most visited archaeological sites, attracting history enthusiasts from around the globe. Source
Naours: The Underground City of France
Beneath the fields of northern France lies Naours, a labyrinth of tunnels and chambers that date back to the Middle Ages. Originally built as a hiding place during invasions, Naours became a sanctuary during both World Wars. Soldiers, particularly during World War I, left behind graffiti that documented their presence, with over 3,000 inscriptions discovered on its walls. According to a 2024 article by the French Ministry of Culture, Naours has become a symbol of resilience and survival. Guided tours now allow visitors to explore its history while learning about its significance during wartime. Source
