This is a list of Hindu temples and their remains in Indonesia. Indonesia has been part of Indosphere of Greater India where sanskritization and Hinduism spread across Indonesia. Hindus in Indonesia are a multi-ethnic society consisting of different Indonesian ethnicities, such as Balinese, Javanese, Indian and other ethnic groups. According to government statistics, the majority of Indonesian Hindus are Balinese that inhabit the island of Bali. This claim has been disputed by one of the leading Hindu bodies of the nation, the Parishada Hindu Dharma Indonesia (PHDI), which estimates there are about 18 million Hindus, indicating that most are not of Balinese origin. There is also a significant Indonesian Indian Hindu minority settled in large cities. Numbers of Indonesian natives that adhere to a form of native Austronesian ancestral and natural worship might also be categorized as Hindus, such as Dayak people (Kaharingan), Batak Karo (Parmalim), Javanese (Kejawen) and, Baduy people (Sunda Wiwitan). Hindu Dayak and Kaharingan groups are concentrated in Central Kalimantan. Types The design, style, layout, architecture and decoration of Hindu temples differ among various ethnic groups. In general, Indonesian Hindu temples are based on the Vasusastra-Manasara, a Hindu text on architecture, though they have significant native and Chinese influence. Balinese Hindu temples do not have the Gopuram above temples unlike Indian Tamil Hindu temples which feature a prominent Gopuram at the entrance. Indian temples are designed as indoor house of worship, while Balinese temples are designed as open-air temple within walled compound connected by series of intricately decorated roofed gates and split gates. In Indonesia, there are roughly three types of Hindu templesː Candi, the Javanese ancient Hindu temples Pura, the Balinese temples Kuil or mandir, the Indian Hindu temples Candi Candi is an Indonesian term to refer to ancient temples, the word originated from the Sanskrit word Candikargha which is associated with the Goddess Durga. Prior to the rise of Islam, between the 5th to 15th century Dharmic faiths (Hinduism and Buddhism) were the majority in Indonesian archipelago, especially in Java and Sumatra. As the result numerous Hindu temples, locally known as candi, constructed and dominated the landscape of Java. According to local beliefs, Java had thousands of Hindu temples which co-existed with Buddhist temples, most of which were buried in massive eruption of Mount Merapi in 1006 AD. Between 1100 and 1500 additional Hindu temples were built, but abandoned by Hindus and Buddhists as Islam
