The presiding deity of the temple is lord Vishnu in his standing posture, similar to the one in Tirupati. The name of this temple is actually Paschima Venkatachalapthi temple as the presiding deity faces west. The area in which the temple is located is called Tirumale. However nowadays it is more popular as Ranganatha temple due to the presence of a small image of Rangatha on the temple wall which is believed to be growing in size every year.
