 Sigiriya

The environment around the Sigiriya may have been inhabited since prehistoric times. There is clear evidence that the many rock shelters and caves in the vicinity were occupied by Buddhist monks and ascetics from as early as the 3rd century BCE. The earliest evidence of human habitation at Sigiriya is the Aligala rock shelter to the east of Sigiriya rock, indicating that the area was occupied nearly five thousand years ago during the Mesolithic Period.

The Gardens of the Sigiriya city are one of the most important aspects of the site, as it is among the oldest landscaped gardens in the world. The gardens are divided into three distinct but linked forms: water gardens, cave and boulder gardens, and terraced gardens.
