Overview of Ancient Underground Cities
Ancient underground cities were intricate subterranean structures established by various civilizations globally. They arose mainly from the necessity for protection and refuge, as well as for spiritual or ceremonial purposes. Different cultures constructed these cities, resulting in a diverse range of architectural designs and functionalities.
These subterranean marvels served multiple purposes. They functioned as safe havens during invasions, storage locations for food and supplies, and sites for communal gatherings. Typically, the construction of these cities took place during periods of conflict or when environmental factors necessitated shelter from harsh weather conditions.
Notable underground cities include Derinkuyu, Turkey, which showcases the complexity of such architectural endeavors. Derinkuyu, dating back to the 8th-7th centuries BCE, exemplifies the capacities of these hidden regions. Originally built by the Phrygians, it expanded significantly during the Byzantine era. This city extends about 85 meters (280 feet) underground and encompasses 18 levels, accommodating up to 20,000 individuals, their livestock, and food stores.
Additionally, the catacombs of Rome represent another remarkable underground site. These extensive burial passages provided refuge for early Christians during periods of persecution. With an estimated length of over 600 kilometers (370 miles), the catacombs feature intricate frescoes and elaborate burial chambers, reflecting the religious practices and beliefs of those who utilized them.
Several other ancient underground cities exist, each revealing unique aspects of their respective cultures. The Cappadocian region of Turkey holds numerous underground complexes used for similar protective and storage purposes. Regions like Malta contain the Hypogeum, a subterranean burial site that dates back to around 4000 BCE.
As interest in these ancient underground cities grows, ongoing excavations and studies occur to unearth their mysteries. These explorations offer crucial insights into the lives of the people who created and inhabited these remarkable spaces. By examining the architectural techniques and social structures represented within these cities, researchers can better understand the historical contexts that shaped ancient civilizations.
Historical Significance

Ancient underground cities hold a crucial place in history. They offer valuable insights into the lives, cultures, and survival strategies of ancient civilizations.
Origins and Development
Origins of underground cities trace back thousands of years. In regions like Cappadocia, Turkey, civilizations constructed these extensive networks as early as the 8th-7th centuries BCE. Techniques utilized in their development demonstrate remarkable architectural skills. For instance, Derinkuyu, one of the largest known underground cities, features 18 levels with ventilation shafts and complex passageways, accommodating up to 20,000 inhabitants. These cities expanded over time, showcasing the adaptability of their creators in responding to threats from enemies and environmental challenges.
Cultural Impact
Cultural significance of underground cities is profound. They served not only as refuge from invasions and disasters but also as communal spaces that fostered social and religious practices. For example, early Christians used the catacombs in Rome for burial and worship, allowing them to maintain their faith during periods of persecution. Similarly, cities like Kaymakli provided a secure environment for communities, allowing cultural traditions to thrive despite external pressures. Ongoing discoveries continue to reveal the rich heritage and social dynamics of the civilizations that constructed these remarkable structures.
Notable Ancient Underground Cities

Ancient underground cities display remarkable ingenuity and serve important historical roles. Noteworthy examples include Derinkuyu, Cappadocia, and the RESO in Montreal.
Derinkuyu
Derinkuyu stands as one of the most famous ancient underground cities, located in Cappadocia, Turkey. Extending approximately 85 meters (280 feet) deep, it could shelter around 20,000 inhabitants along with their livestock and food supplies. Derinkuyu features advanced amenities, including wine and oil presses, stables, cellars, storage rooms, refectories, and chapels. A sophisticated ventilation system ensured air circulation throughout the complex, while large rolling stone doors provided security, enabling closure from the inside. Initially constructed by the Phrygians in the 8th-7th century BC, it underwent expansions during the Byzantine period. Derinkuyu offered refuge from various threats, including Arab Muslim invasions and Mongolian incursions, and interconnected with the underground city Kaymakli through extensive tunnel systems.
Cappadocia
Cappadocia encompasses multiple ancient underground cities, characterized by unique geological formations. These subterranean structures provided crucial protection against invasions and harsh climates. Cities like Kaymakli, in addition to Derinkuyu, highlight sophisticated architecture designed for habitation and defense. The region’s volcanic rock allowed for easy excavation, facilitating the construction of multi-level living spaces, storage areas, and communal halls. Today, Cappadocia serves as a prominent historical site, attracting scholars and tourists seeking insight into the remarkable civilizations that created these underground networks.
Montreal’s RESO
Montreal’s RESO, also known as La Ville Souterraine, represents an extensive underground complex combining shopping centers, residential buildings, and transit systems. Spanning over 33 kilometers (20 miles), RESO connects various downtown locations, enhancing urban life during harsh winters. While not ancient, RESO’s construction started in the 1960s and reflects modern urban planning strategies that prioritize climate adaptability and convenience. This extensive network draws millions of visitors annually and serves as a significant cultural and commercial hub in Montreal, showcasing how underground spaces continue to evolve.
Architecture and Engineering

Ancient underground cities exhibit remarkable architectural and engineering practices, showcasing the creativity and resourcefulness of their builders. These structures were not only functional but also designed to withstand environmental challenges and threats.
Construction Techniques
Constructed primarily by carving soft volcanic rock, ancient underground cities utilized techniques that adapted to the geological conditions of their locations. In Turkey’s Cappadocia region, builders likely began this practice during the 8th-7th century BCE, initiated by the Phrygians and further developed in the Byzantine era. Derinkuyu demonstrates this approach, with approximately 85 meters (280 feet) of depth and 18 levels, all meticulously hewn from stone. These techniques allowed for the creation of vast subterranean complexes that could accommodate large populations, livestock, and food storage.
Design Features
The design of ancient underground cities prioritized functionality and defense. Derinkuyu, for example, housed up to 20,000 people and featured a sophisticated ventilation system, ensuring airflow throughout its extensive network. Kaymakli, another underground city in Cappadocia, exemplifies complexity with its interconnected tunnels and chambers utilized for agricultural storage and trade. Architectural elements, such as large stone doors and narrow passageways, enhanced security, enabling inhabitants to repel invaders effectively. The intricate design facilitated communal living, community activities, and the preservation of cultural traditions amidst potential threats.
Modern Discoveries and Research
Ongoing research and archaeological discoveries reveal intricate details about ancient underground cities, deepening understanding of their historical and cultural significance.
