If you are studying Hindu art and architecture, Hindu temples are a good place for students to start. The Huffinton Post has a great slide show of "30 awesome Hindu Temples." Religion Facts and a site called Indotemple.com both have good background.
Hindu temples reflect both the time period in which they were built and the location. The Brihadeeswarar Temple above, located in the Indian state of Tamil Nadu is dedicated to the Hindu god, Shiva. It is a UNESCO World Heritage site and is one of the largest Hindu temples in India, if not the largest. It was built in 1010 CE and is often called "The big Temple."
The Changu Narayan Temple, located in the Bhaktapur district of Nepal is part of the Group of Monuments at Kathmandu Valley. It is the oldest temple in Katmandu and dedicated to the Hindu god, Vishnu. The clip below allows you to take a virtual tour of the temple.
