Puri is one of the seven most holy places for Hindus in India. Puri is the site of the Govardhana matha, one of the four cardinal institutions established by Adi Shankaracharya, the others being those at Sringeri, Dwaraka and Jyotirmath. Puri is also famous for its annual Ratha Yatra, or Festival of Chariots, when the deities Jagannath, Balabhadra, and Subhadra, are brought out of the temple, and placed in a chariot procession. This festival occurs on various dates of the Gregorian calendar, typically in the month of July. The town is famous for its many Mathas (Monasteries of the various Hindu sects). It also houses the relics of many Hindu figures as traditionally it is seen as a holy place to die in or to be cremated. As a result, it has had a disproportionate number of widows.
