Built in 1809, the Kali temple is one of the most significant pilgrimage sites in India, with shrines to Shiva, Krishna, and Kali, the patron goddess of Kolkata. Human sacrifices were reputed to be commonly practiced here on special days during the 19th century, but only goats are slaughtered now, then offered to the goddess with bhang (marijuana). The building rewards a close look: you'll see thin, multicolored layers of painted trim and swaths of tilework. Only Hindus are allowed in the inner sanctum, but the lanes and brilliant flower markets surrounding the temple are lovely in themselves. Beware of touts and aggressive priests.
