Visitors to Derinkuyu can embark on a guided tour to explore the labyrinthine passages and chambers, gaining insights into the daily life, religious practices, and defensive strategies employed by the inhabitants of this subterranean marvel. The tour typically begins at the entrance, where a narrow staircase leads down into the depths of the underground city. As you delve deeper, you'll encounter a complex network of rooms that served various purposes, including living quarters, communal areas, storage rooms, stables, and places of worship. The ventilation system, wells, and ingenious engineering solutions for water supply and waste disposal reflect the advanced planning and construction skills of the ancient inhabitants. One of the most intriguing aspects of kaymakli is its extensive tunnel system, designed not only for movement within the city but also as a defensive mechanism against potential invaders. Massive stone doors, some weighing several tonnes, could be rolled into place to seal off different sections, preventing unauthorised access and providing protection during times of danger.
