Sigiriya Rock Fortress is utterly impressive. The rock walls rise up 200 meters from the ground, only to give way to a flat plateau at their summit. There are steep stairwells to reach the top and many frescos to marvel at on the way up. At the top, you can find the remains of an ancient civilization, including relics of a palace and monastery. It would have taken true engineering ingenuity to build a structure at this height so many centuries ago. Around the rock fort are many important caves and gardens; impressively, they are some of the first landscaped gardens in the world.
