Note: Harihar temple of Osian, Neelkanth temple of Rajorgarh, Adivarah temple of Ahad and Harshat Mata temple of Abhaneri were built during the period of Gurjar-Pratihar. Pratihara ruler Mihirbhoj was a follower of Vaishnavism and adopted the title of 'Adivarah' and 'Prabash'. The ancient, artistic temple of Harshat Mata is in Abhaneri. Abhaneri is famous for Harshat Mata temple and Chand Bavari. Statues of almost all main Hindu deities are found here. These magnificent statues of around 8th-9th century were related to Gurjar-Pratihar rulers of this area.
