Tirupati city in Chitoor district, Andhra state  is one of the most prominent places of pilgrimage in India and it is often said that the city never sleeps since pilgrims in thousands arrive in this city day and night from different parts of India  to go to the Balaji temple atop the hill of Tirumala.  There are no Hindu families or their relatives in India who have not been to Titupati, one  can say emphatically. 

Located in the heart of the city in  Tirupati (down) is an historical temple dedicated to Sri. Govindaraja Perumal and one can not miss the impressive, majestic gopurams. - towers. It is believed to be one of the earliest temples in Chitoor district and the temple complex is a big one. The tradition has been that the pilgrims are supposed to visit this temple and the Thayyar (goddess) temple at Alamelumanga Puram, before  visiting Balaji temple up on the hill. Built in the 12 th century, Saint Ramanujar reconsecrated the idol of Govindaraja Perumal in 1130 AD. But,  the temple complex belongs to the 9th and 10th centuries. Earlier, the presiding deity was lord Parthasarathi (Lord Krishna who rode the chariot for Arjuna in the Kurushetra war).
