Pura Ulun Danu Batur is a Hindu Balinese temple located on the island of Bali, Indonesia. As one of the Pura Kahyangan Jagat, Pura Ulun Danu Batur is one of the most important temples in Bali which acted as the maintainer of harmony and stability of the entire island. Pura Ulun Danu Batur represents the direction of the North and is dedicated to the god Vishnu and the local goddess Dewi Danu, goddess of Lake Batur, the largest lake in Bali. Following the destruction of the original temple compound, the temple was relocated and rebuilt in 1926. The temple, along with 3 other sites in Bali, form the Cultural Landscape of Bali Province which was inscribed as a World Heritage Site by UNESCO in 2012.

Subak is the water management (irrigation) system for the paddy fields on Bali island, Indonesia. It was developed in the 9th century. For the Balinese, irrigation is not simply providing water for the plant's roots, but water is used to construct a complex, pulsed artificial ecosystem that is at the same time autonomous and interdependent. The system consists of five terraced rice fields and water temples covering nearly 20,000 hectares. The temples are the main focus of this cooperative water management, known as subak.
