Akshardham, New Delhi, built 2001-2005. By most measurements the largest Hindu Temple in the world.
It is dedicated to Swaminarayan (1781-1830), the founder of the Swaminarayan sect of Vaishnavism, who is considered an incarnation of Purushottama (the supreme deity) by his followers. The name Akshardham refers to the divine abode of Swaminarayan, where the soul goes to attain moksha (liberation).
