A tunnel is a man-made underground passage that provides a direct route between two points, bypassing obstacles such as mountains or bodies of water. Tunnels have been utilized for centuries as a means of transportation and connectivity. They can vary in size, shape, and construction material, depending on their intended use. The excavation and construction of a tunnel require careful planning and engineering to ensure safety and stability. Some tunnels are equipped with lighting, ventilation, and drainage systems to facilitate passage. Additionally, there are tunnels without authorship, created by nature through processes like erosion or volcanic activity, which serve a similar purpose of connectivity and access. The history and significance of tunnels without authorship are also fascinating to explore.
