The Sigiriya Water Gardens form an important part of the ancient royal city built around Sigiriya Rock during the 5th century AD. They are located in the western precinct at the base of the rock and are considered among the oldest surviving landscaped gardens in the world. The gardens are arranged along a symmetrical east-west axis and are divided into three principal sections. The first garden includes water-surrounded areas, pathways and gateways. The second garden features two long pools, shallow winding streams and circular limestone fountains. These fountains are supplied by an underground water-conduit system and can still operate during the rainy season. The third garden is situated at a higher level and contains an octagonal pool and raised platform. The gardens are connected to the surrounding moat and ancient water-management system. Their design demonstrates the engineering knowledge, artistic creativity and landscape-planning skills of ancient Sri Lankan builders.
