Also known as Vada Kailasam (the place of five rivers), the Uttara Kailasa temple of the Pancanadisvara complex was built by Rajaraja I's (985 – 1014 CE) senior queen Danti Sakti Vitanki alias Loga Mahadevi in about 1006 CE. This temple is significant for it bears an inscription from the reign of Rajadhiraja I (1018-1054 CE), which gives a complete narration of the wars and the victories of the Chola king elucidating contemporary political events and the extent of the empire.
