These tunnels prove beyond doubt the architectural brilliance of King Ravana. These tunnels served as a quick means of transport through the hills and also as a secret passage.
These tunnels networked all the important cities, airports and dairy farms. A .close look at these tunnels indicates that they are man-made and not natural formations. This Buddhist shrine at Kalutara was where once King Ravana's palace and a tunnel existed. Existing tunnel mouths are situated - Isthripur at Welimada, Ravana cave at Bandarawela, Senapitiya at Halagala, Ramboda, Labookelle, Wariyapola/Matale, and Sitakotuwa/Hasalaka. In addition there are many more tunnels.
